3. There is no specific music or genre i stick on to all the time when im calm or relaxed.I love to relax myself with some ambient music,or even soft pop-rock genre.if its indian music,its hindustani that i would vote for.i also like certain carnatic artists that i lend my ears to ,when i want to relax.For me i guess its an ever-changing thing.The genre of music that i might listen to when i want to relax.It depends on my specific state of mind.I also make it a point to listen to music by other composers to know whats happening in the industry and who is doing some good works.But mostly that will be a 1-2 time listen to the max.
4. You cant really compare the two roles.I would say a composer is father a lyricist is mother and the singer or singers are the kids who carry bring the music to the world or make a composer or lyrcists proud.
A composer should have following knowledge i would ideally say.
-He should atleast be exposed to different forms and genres of music.Atleast an exposure will do wonders sometimes.
Different genres could be western,classical,native,folk etc...!!!
-If he knows music or has music training in any of the classical forms,he will ideally know what is going on in his music rather than just hummed tunes and melodies.
-If he can translate his ideas to his singer in one form or the other(singing or instrument),he knows his job well.These days,you can have an assistant to do that job for you.
-If he knows to program or sequence music,he could attach himself to the genre of newage composers who are technically fit too.
-If he knows to update himself to the latest technologies and genres,he is actualy doing even better.
-He should also be able to look at music from a top angle where he knows what each element means and how they add on to the totality of the composed piece.
For eg, a singer might not know what the music may actually sound like when it will come out.These days(ARR started that trend),sometimes,a singer is given only click sound and a sruthi and made to sing,he/she has no clue what is going to happen afterwards.But the right selection of singer means...a composer has chosen the right vehicle for his music to traverse across to the listener to give him the most engaging experience of music.
But still i would dare to say that,no classical music experience is compulsory in any type of music composing.If your heart can hum great sounding sweet melodies which can make someone happy...or make someone dance with joy...or even bring a tear or two into someone's eyes......then "yes", you are a gifted musican...gifted from god.No learning or Certificate is required for that.
A singer who can contribute to the overall musicality of the song is a BOON.for eg,people like sankar mahadevan and hariharan contributes a lot to a song.
What they do is not mere reproduction of a half baked tune.They hear the song,they hear the arrangement,and they give their version of what they feel is the best.In fact they give you lot of options to experiment with.With such incredibly talented singers,there is always a chance for the music to evolve...from a stale..fixed notated tune to a much breathing...fuller musical journey.
