I used to (when it was first coined) do that in the 60's and early 70's. Then I got into writing them for other voices. From there, I went to writing for a particular voice, and now I'm composing more of larger works. I did a soundtrack for a film, in which incorporated several styles, and genres,..and did it very well and authentic to their particular style, if I do say.....(clears throat)....What is important to remember, is that music is a communication, and to communicate, with accuracy, just exactly what is is you wish to convey, so the listener, participates to some degree in your experience. To merely write, as to fulfill some notion of 'how you fancy yourself', or wish to be seen, is rather self indulgent, and that comes across too (whether you think so, or not).

Here's a link, to a fantastic song, in where the composer wrote for another voice,...the words and feeling conveyed say so much more, just in what is implied. The composer is David Downes, also the pianist, seen in the video. Singer is Lisa Kelly.

If ever there was a song that conveyed an inner desire, for a song, from a composer, this is it! Enjoy!!
