Filmy Ripples – Messiahs Embedded Lyrics

By P.V. Gopalakrishnan

Film lyrics could be anything these days, for the lyrics are ever drowned in the racy BGM that appeals to the foot-tapping dance, resulting in the loss of intrinsic value of the songwriter. Even a decade or so back the situation was not this pathetic.

But the old movie lyrics stood out as the music was conducive to the words of the lyricist. In fact, many songs of the yesteryears are remembered to date by their evergreen lyrics.

Old songs often carried messages, useful to the community at large; And when these songs were delivered by the larger than life Stars of those times, they had an immaculate impact on the cine goers.

In this edition we would strive to look at some of such songs that carried good messages. In fact, there were too many such old songs that carried messages. However, we cherry picked some of them from different time frames, for our feature here.

N.S.Krishnan used to convey messages for the society through his comic coated songs always in the lyrics of Udumalai Narayana Kavi. One such was ‘Vatham vambu panna koodathu’ from the film “Dr.Savithri” (1955). The song, composed by Music Director G.Ramanathan, was directed as advice to married women, though not very relevant to the current generation, manifesting Bharathiyar’s ‘pudumai penn’!

In the bygone days, children had reverence for parents almost bordering on a fringe of fear about them. They were taught too that parents & teachers were equivalent to almighty. The values were different then.  Generations have since changed when most parents now have a single child or two to whom they afford the best in life & the children too, in turn, move with them more like a demanding friend. That reverential gap has since evaporated. Here is an old time’s song ‘Matha pitha guru deivam’ from ‘Naan petra selvam’ (1956), in the voice of A.P.Komala, the music being by G.Ramanathan.”

‘Aadi paadi velai senja’ from ‘Enga Veettu Mahalakshmi’ (1957), in the music of Master Venu, brings out the sterling fact that work done without pressure becomes a pleasure. The same has been recognized by mighty organizations that even play piped music to increase the productivity of its workers in shop floors as well as offices. The humble agrarian workers, labourers drawing mighty loads & hard sailing fisher folk – all of them – resort to singing in order to lighten their work strain. The modern housewives, whenever they have to cook in the kitchen or drive to work naturally resort to their favourite FM! The singers of the subject were Ghantasala & P.Suseela and the lyricist was Udumalai Narayanakavi.

‘Sinthanai sei maname’ was an iconic song advising minds to have balanced views to get rid of evils. Sung by TMS, it was from ‘Ambikapathi’ (1957), produced by ALS Productions. The musical treatise was by G.Ramanathan’ & the lyricist was K.D.santhanam.

The innumerable instances where the alcoholics bring misery to their household, especially to the wives, have been the subjects of many films with a social cause. The film ‘Anbu Engey’ (1958) had a beautiful song with such a message ‘Ethanai kodi panam irunthalum’ in the pristine voice of P.Suseela. The music was by Vedha on the lines of Kannadasan.

‘Aathile thanni vara’ by Sirgazhi featured in modern Theatre’s ‘Vanna Kili’ (1959) in the lyrics of Maruthakasi & set to music by K.V.Mahadevan.’ Life has plentiful surprises both pleasant and otherwise. These have no explanations, which makes life unique. This has been the subject of this song.

The songs in MGR starred movies used to carry lot of messages. One such was ‘Chinna payale’ from the Jupiter’s film ‘Arasilamkumari’ (1961) in the lyrics of the inimitable Pattukottai Kalyanasundaram, who died very young. He was an understudy of Poet Bharathi Dasan. The song gives Do’s & Don’ts to the child to whom it is addressed. The music was by G.Ramanathan.

Another character building song directed at kids was ‘Thirudathe papa thirudathe’ from the MGR film ‘Thirudathe’ (1961) in the voice of TMS, while S.M.Subbiah Naidu scored the music on the lyrics of Pattukottai Kalyanasundaram.

‘Engalukkum kalam varum’ was an inspirational duet song, by P.Suseela & TMS, etched in Positive Thinking from the iconic movie ‘Pasa Malar’ (1961), Kannadasan holding the fort for its lyrics. MSV-TKR composed the music.

‘Budhiulla manithar ellam’ rendered by Chandrababu from the AVM produced film ‘Annai’ (1962) had the music of Sudarsanam. The song illustrates the vagaries of life where cohesive things always do not exist.

Often film makers used to have off-screen songs which practice has dwindled over the time. One such song ‘Mayakkama kalakkama’, was very touchingly rendered by P.B.Srinivas in Sridhar directed ‘Sumai Thangi’ (1962) in the lyrics of Kannadasan.  The lyrics are just beautiful and about resolving mind games by lateral thoughts.

‘Dharmam thalai kakkum’, written by Kannadasan &  sung by TMS, was the Title Song of the Sandow Chinnappa Devar produced film of the same name, starred by MGR, who doles out a message with a song even as he drives. This movie of 1963 was given music by K.V.Mahadevan. The nobility associated with charity is highlighted to the masses by the song.

Money has overtaken the principles of life in today’s life. It is only increasing its velocity of such rate of overtaking over the years. ‘Kurangu varum thottamadi’ in the voice of TMS from the G.N.Velumani produced film ‘Panathottam’ (1963) vividly portrays this status. Music composed by MSV-TKR, this song has the golden words of lyricist Kannadasan.

Though all such songs as featured above must be appealing to listen even now, such genre has lost connect in today’s terms, with the current mass scale departure from what were routinely advocated & accepted things in the past.  Thanks to cultural change!

Filmy Ripples- Exotic Instruments in Film music – Part 5 (Final)

By P.V. Gopalakrishnan

In this concluding part on Exotic Instruments in Film Music I wish to share some of my thoughts on our classic numbers in Tamil Film Music from the bygone era, listening to which we get transported back to relive the past!

They make us visualize the mammoth orchestra that went with the recording of many of the classic songs. This in turn trigger our thoughts on those times when these melodies were made. By any count, people mostly agree that these oldies from the world of Indian Film music are indeed a treasure.  The melodies of these songs are as fresh as the morning breeze to us forever. Added to them, the fine lyrics & clear diction of the singers make them so memorable.

This writer has had, during his prime days, the opportunity of witnessing few song recordings, thanks to a peer with connections! Those days were prior to the advent of stereo. The musicians were so cramped in a small recording room. Often the instruments they played on, per se, were hugely cumbersome, whether it is Univox, Double Base, Vibraphone, Piano, Cello, Kettle Drum or Harp. The air-conditioning was mostly absent as they wanted to be free from the noise of room air-conditioners & the central cooling system was not in vogue then. Imagine these very classic melodies, that were made in such less friendly environs, are being crooned out over stereophonic mikes with mixing facilities by today’s participants of TV Reality & stage shows, in the air-conditioned comfort. Whereas those men who played this music in perfect harmony, recorded them so truly sweating them out.

Those were the days, not blessed with digital sound technology. Nor were sound files & bytes known. The recordings were done the hard way. Thanks to the non-advent of track recording, the singers were in full human form & feeling the real music emanating from physically played instruments by a swarm of musicians. This meant a lot of understanding, respect & harmony between the singers & the players. The real human side of the collective music, if you like.

The music so generated also had passion in its roots having been delivered by talented musicians in real time recording situations. These unplugged sounds of the music were pure & original from each instrument, whether wind, brass, string or percussion. These great melodies were captured by “shure” mikes of mono format & made captive in vinyl record discs of those times, in the avatar of LPs & EPs. There were no computer generated beats, no octopus pads & no synthesizers, which today form, at best, poor imitations of the reverberations of the original instruments.

Some of the legends of sixties in the Tamil film music world included doyens like Sabesan (pianist), Raju (mandolin), Henry Daniel (trumpetist), Sudarsanam (flute), Philip (guitarist), Mangalamurthy (accordian), Hanumanthayya (tabla), who were all over the immortal compositions of the duo Viswanathan – Ramamoorthy. These guys were behind each of the old time melodies & many of them have left this world since leaving a huge vacuum!

With limited medium of entertainment (TVs, other recorded devices made advent much later) all ears were glued to those radio sets listening to Radio Ceylon and these musicians lived up to the responsibility of delivering the sole audio entertainment of those days. And they did it with aplomb, in unmatched quality!

Listening to these old melodies bring you nostalgia, laced with a tint of sadness of having lost those days forever in one’s life! A sadness of a like which is as soothing as weeping!!

But, it is unfortunate that these classic film musicians did not directly see themselves in limelight & withered away unacknowledged largely, though Groups like MSV Times bring honor to some of them either live or posthumously.

Now on to discuss the individual musical instruments that played in well known songs.

Dholak is a double sided folk drum, usually played with both hands while positioned on the player’s lap while an iron thumb ring is used to produce a distinctive rim sound as rhythm.

In many old Tamil songs, one used to hear Dholak beats and here is ‘Ullathile uram vendumada’ rendered by A.M.Raja from Vijayapuri Veeran, composed by T.R.Paappa, for your listening pleasure. (1960)

The beautiful duet, ‘Anbu manam kanindha pinne’ (Aalukkoru veedu -1960 Film) too has Dholak percussion through the song.

‘Dafli’, as it is called in Hindi, is a Tambourine, denoting an instrument with a large circular drumhead, on which skin membrane is stretched over the playing area. In Tamil, it is colloquially known as ‘Tape’. In Hindi a full film called ‘Sargam’ was dedicated to it, with Rishi Kapoor as a Dafli player. Here is a popular Tamil song, ‘Ellorum kondaduvom’ by TMS from ‘Pava Mannippu’, composed by MSV-TKR.

The Western Drum Set has also been often used in Indian film music. Here is an instance of its deployment in ‘Kannirendum minna minna’ from ‘Andavan Kattalai’, rendered by P.B.Srinivas & L.R.Easwari. The composers MSV-TKR have used it along with Piano Chords through the song. Mr. Noel Grant was the ace drummer who worked in the orchestra of MSV-TKR.

Snare Drum, which is part of the main Drum Set, is played by striking it with either a drum stick or any other form of beater, including brushes which produce a softer-sounding vibration from the snare wires. Our composers have used Snare Drums in many songs. Here we can hear it in the song ‘Sugam…sugam’ from the film ‘Thangai’  (1967) composed by MSV.

Ghatam is an instrument used in carnatic stream of music & is one of the most ancient percussion instruments of South India. It is a clay pot with a narrow mouth. From where, it slants outwards to form a ridge. Made mainly in Manamadurai (Tamil Nadu) & Devanahalli (Karnataka), of clay with with brass or copper filings along with a small amount of iron filings, it’s a fixed pitched instrument.  It has been made international by the Ghatam Wizard ‘Vikku’ Vinayakaram, who holds even a Grammy Award.

‘Azhagana Ratchasiye’ composed by A.R.Rahmam for the film ‘Muthalvan’ has ample usage of Ghatam. Dr.Karthick has played ghatam for A.R.Rahman in some of his compositions.

Veena is an instrument that relates to historical past, which is used in Carnatic stream. However, artistes like Chittibabu, Parthasarathi & Rajesh Vaidya have done some excellent work, playing for various composers in Tamil films.

We cite here two Tamil film melodies featuring Veena, ‘Sonna sollai nee’ by M.S. Rajeswari, from ‘PeNN’ composed by Sudarsanam & ‘Deviyar iruvar’ from ‘Kalai Koil’ composed by MSV-TKR. The latter film featured copious Veena notes in its songs as well as BGM, as the Hero was shown as a Veena artiste. These were played by the late Veteran Chittibabu, whose disciple is Rajesh Vaidya.

Gottu Vadhyam aka Chithra Veena is another traditional string instrument of great antiquity, popular with Carnatic music. This stringed instrument which resembles a Veena, is played by a slide just like a Hawaiian Guitar. Dr. Ravikiran is a well known exponent of the same. There have been few songs using this instrument. The Malayalam song ‘Senthar mizhi’ from ‘Perumazhakalam’, composed by M.Jayachandran features Gottu Vadhyam strains along with Ghatam beats, very creatively.

Piano too has been abundantly used in our films, particularly in South by MSV-TKR. MSV himself was very good at playing Piano. ‘Brindavanamum Nandakumaranum’ (Missiyamma), ‘Pattunro kaetten’ (Pasamalar), ‘Paaduvor padinaal’ (Kannan en kadhalan), Unnai onru ketpen, (Puthiya Paravai) Kannirendum minna minna (Andavan Kattalai), Ellorum nalam vazha (Enga Mama), Enna enna varthaigalo (Vennira Aadai) , Manithan enbavan (Sumai Thangi) , Kannenna Kannenna kalanguthu (Periya idathu peNN).

‘Glockenspiel’ aka ‘bells, as is commonly referred to, is an instrument of German origin, having metal plates or tubes as ‘keys’ and are played by striking upon with hard tippled mallets, thus making it a metallophone. Our South Indian Composers have often used it in their songs, especially MSV-TKR duo. Listen to ‘Muthukkalo kangal’ (Nenjirukkumvarai) or ‘Thookkam kangalai’ (Alayamani) where this instrument makes very delectable notes.

Here is Harry Potter theme played on a Glockenspiel.

Vibraphone is a larger version of a ‘bells’ and has deep resonance of the notes produced which have a tremolo effect. The following video gives an idea of this instruments & its way of playing.

There are plenty of Tamil film songs where they have used this instrument. Here is an instance where Vibraphone has been used, the song being ‘Varathiruppano’ (Pachai Vilakku), rendered by P.Suseela in the composition of MSV-TKR.

Filmy Ripples – Exotic Instruments in Film music – Part 4

By P.V. Gopalakrishnan

In this concluding part on the above caption, we would strive to feature & discuss about some more of the exotic musical instruments used in our film music.

Trumpet is another popular wind instrument to form a part of the Brass Section of an orchestra, which has been in use in Indian films for a long time.

MSV-TKR has used Trumpet bits in many of his compositions, notables of which include ‘Thulluvatho ilamai’, ‘Adho andha paravai pola’ & ‘Unnai onru ketpen’.

Kishore Sodha has been a reputed trumpet player in Bollywood since 1978 and had worked for composers such as R.D Burman, Kalyanji-Anandji, Bappi Lahiri, Anu Malik, Laxmikant-Pyarelal, Anand-Milind, Shankar-Ehsaan-Loy and more.  His first song on trumpet accompaniment was ‘Rote Hue Aate Hain Sab’ (Muqaddar Ka Sikandar).

The Trumpet is also used placing a ‘mute’ in its ‘bell’ portion so that the sound emanates from there in a muted form. If you hear ‘Maan kanda sorgangal’ from ‘47 Naatkal’, composed by MSV, there are notes from a muted trumpet throughout. The following video explains about a muted trumpet.

Saxophone is an amazing wind instrument, grouped again under Brass Section in Western Orchestra. It was invented in 1840 by the Belgian instrument maker Adolphe Sax, after whom it is named.

Sax, as it is called in short form, it has been used in many compositions such as ‘Unnai onru ketpen’ (Puthiya Paravai) composed by MSV-TKR, ‘Ammamma keladi thozhi’ (Karuppu panam) by MSV-TKR & ‘Vannam konda vennilave’ (Sigaram) composed & sung by SPB.

Puthiya Paravai

When we talk of Sax in film music, we cannot but mention the late Manohari Singh, a Sax wizard of Nepali  origin, who had played for leading Hindi composers in immortal songs such as ‘Gatha Rahe mera dil’ (Guide) by Sachin Dev Burman & Yeh Duniya usiki (Kashmir ki kali) by O.P.Nayyar.

Another beautiful composition of S.D.Burman featuring Sax was ‘Oh mere jeevan sathi’ from the movie ‘Guide’.

In the film ‘Duet’, A.R.Rahman had the classical sax player, Mr. Kadri Gopalnath, to play through the film. This film, in fact, popularized this instrument.

Trombone is a Brass wind Instrument, the sound of which is produced when the player’s vibrating lips cause the air column vibrate inside the instrument, having a telescoping slide mechanism that varies the length of the instrument to change the pitch.

While Trombone is usually played in Brass bands – accompanying the main theme by giving punching phrases, the potential of this instrument to perform as solo cannot be undermined.

Here is a piece on Trombone playing Michael Jackson’s ‘Thriller’.

In Indian films’ BGM scores, Trombone is usually played together with other brass instruments. They have had limited scope as a solo in the interludes of movie songs.

In songs such as ‘Ulagathil siranthathu edhu’ (Pattanathil Bhootham), ‘Atho antha paravai pola’ (Ayirathil oruvan) & ‘Kalyana naal parkka’ (Parakkum Pavai) you could hear Trombone bits. Here is the latter song in the composition of MSV-TKR.

Pattanathil Bootham

Ilaya Raja’s ‘Ennamma Kannu’ too had Trombone predominantly.

Oud is a short-necked, pear-shaped multi-stringed musical instrument belonging to Lute family, used in Middle Eastern & North African music.

You can rarely hear Oud in Tamil film music.  Ilayaraja’s ‘Matha un kovilil’ from ‘Achani’ (1978) had distinct Oud usage along with Bells in its BGM. Another good usage could be spotted in the A.R.Rahman composed song from ‘Ravanan’

Achani

Maraca is a rhythm instrument of Mexican origin used in Latin American & Rumba music. It is a humble instrument originally made out of gourd shell.

We can spot the rhythmic sounds of Maraca in many film songs if we very carefully listen, but often it gets submerged in the BGM in most of the songs. Here we have selected a Hindi song, ‘Mujhe duniya wale’ by Mohd. Rafi from the film ‘Leader’ (1964) in the music composition of Naushad Ali, where one can make out the ‘chik-chik’ notes raised by Maraca in rhythmic pattern.

Mexican Scratcher is another humble but exotic rhythmic instrument used in Latin American music & Salsa.

R.D.Burman was the pioneering Music Composer to use it in Indian film music when he used it in the poular song ‘Samne wali kidki pe’ from ‘Padosan’. It features very prominently in the song when Keshto Mukherji enacts with a broom, in the early part of the song.

Another exotic but humble instrument called ‘Elathalam’ is a Clash Cymbal used in Temple Music in Kerala. It is a pair of heavy brass cymbals played with one held firmly & the other clashed with it rhythmically.

A.R.Rahman has creatively used it in the song, “Narumugaiye” in the movie ‘Iruvar’. You can hear this bit in the said song when the visual of the hero & heroine appear in the waterfalls sequence.

In our 5th & concluding part of ‘Exotic Instruments in Film music’ next week, we would look at few more of the instruments used in film music.

Filmy Ripples – Accordion in Film Music

  By P.V. Gopalakrishnan

In the early times when classical music was by far the stronghold in cinema, the orchestras, which were mostly owned in-house by Production Houses, comprised, mostly, traditional Indian musical instruments, including Harmonium & Jalatharangam.

Listen to this song by K.B.Sundarambal from the cult classic film ‘Avvaiyar’ (1953), in which Jalatharangam features along with violins.

Another old song where the BGM, which included Harmonium is minimalistic was from the film “En Manaivi” (1942), featuring Nellore Natesam.

Some of Western & African instruments were also in used in the Tamil movies produced prior to fifties, such as Clarinets, Trumpets, Violins, Piano et al.

Here is an old hit from Vazhkai, in which you could hear Clarinet dominantly in the BGM.

In fact, till much later, Clarinet solos featured in many Tamil film hits, like the song ‘Inbam Pongum Vennila’ from Veera Pandiya Kattabomman, composed by the legend G.Ramanathan. You can hear clarinet in this song in the opening music itself after Sitar, Violins & Univox, in that order.

The Magnum Opus production, “Chandralekha” (1948) by Gemini Vasan had its soundtrack composed by S.Rajeswara Rao with R. Vaidyanathan and B. Das Gupta collaborating with M.D.Parthasarathy  on the background score. In an old interview with ‘The Hindu’, Rajeswara Rao had recalled that it took him over a year to compose the music for the film, with much of the time being taken for the drum dance sequence. He stated that the music for the mammoth Drum Dance sequence they had used Trumpets, piano, many Double Bass violins and drums from Africa, Egypt, and Persia acquired from a visiting African war troupe. Cooling Rajiah played the Accordion & Piano in the gypsy song in the same film.

In the Post Independence era, the Tamil movies started seeing changes in terms of story subjects, the way dialogues were delivered & even the music compositions, in tune with the overall metamorphosis that was witness to the change of air, all around.

The music directors were ever ready to bring in new music instruments into film music.

Though Tamil Cinema, despite being the big brother of other Southern Regional Filmmakers, traditionally followed trends in Hindi film industry.

The sensational Rajkapoor film ‘Awara” (1951) had Musical notes that was thought to be Accordion notes, which distinguished the song “Awara Hoon” by Music Directors Shankar-Jaikishen duo, inspired by an old Turkish tune.

However, there is a theory that the notes were, in fact, not Accordion at all but was played on Harmonium by one Vistasp Balsara, who passed away in 2005. He claimed, in an interview to Calcutta Doordarshan, to have played such Harmonium pieces also in other classics such as “Yaad Kiya Dil Ne” (Patita, 1953) and “Aye Mere Dil Kahin Aur Chal” (Daag, 1952).

But Accordion has come to stay by then as an important cine instrument in Hindi. Here is another breezy number from another Rajkapoor starrer, ‘Dastan’, where notable Accordion notes by the player Goody Servai decorate the song composed by Naushad.

There were other noted Accordionists in Hindi Film Industry such as Kersi Lord (Roop tera mastana in Aradhana), Sumit Mitra (Har Dil jo pyar karega in Sangam) Enoch Daniels (Beqrar karke hame from Bess saal Baad). Of these we have to specially mention about Late Kersi Lord, who was a multi instrumentalist & who immortalized some of the Hindi film hits with his contribution. He was honoured with Dadasaheb Phalke Award in 2010, as a cine musician. He was the one who played the bells like sounding ‘Glockenspiel’ instrument in the famed song ‘Main Zindagi Ka Sath Nibhata Chala Gaya’ composed by Jayadev in ‘Hum Dono’.

The accordion thus became an oft-used instrument in Hindi cinema under legendary Music directors such as C Ramchandra, Naushad, Shankar-Jaikishan, Salil Chowdhury and S D Burman as they made it a part of their compositions.

It was in Pava Mannippu (1961) that MSV-TKR featured Accordion in ‘Athan….En athan’ composition & the  Accordionist was our own Mangalamurthy.

Accordionist Mangalamurthy was this writer’s craft teacher in the high school, in the late fifties, but owing to his parallel music career he was hardly seen in the school and was on long leave.

MSV had used Accordionist Mangalamurthy in many of his compositions. Some of the songs where Accordion has predominantly featured are “Avalukkenna” (server Sundaram), “Ulagam piranthathu enakkaga” (Paasam), ‘Kannirandum mella mella’ (Andavan Kattalai),  Ponaal pogattum poda (Palum Pazhamum), “Netryvarai nee yaro” (Vazhkkai Padagu), “Unga ponnana kaigal” (Kathalikka Neramillai), “Poranthalum ambilaiyaa” (Policekaran Magal), “Kan pona pokkile” (Panam Padaithavan), “Iyarkkai ennum ilaiya kanni” (Shanthi Nilayam), “Varavu ettana” (Bhama Vijayam), “Naalai intha neram parthu” (Uyarntha Manithan).

In the following video of Avalukenna song, Mangalamurthy features himself playing accordion, along with his other legendary co musicians, such as Philip (Guitarist) & Raju (Mandolin/Santoor/ Yodelling).

The accordion’s origin is said to be from Berlin & this heavy instrument, worn on the player’s chest, weighs about 7 kgs.

A R Rahman gave Accordion a home coming again & his accordion could be heard throughout the film Guru & even in his Tamil composition ‘Nenjukkulle’ from the film ‘Kadal’.

We will talk about some more veteran cine musicians from old Tamil Films & their exotic instruments in our upcoming articles.
