Azizi,

This is a great thread. What we know of folk music came from people who may not have had concert voices but sang for their own pleasure. If it wasn't for this, we would not have had a folk music revival here or other places. Many "informants" who were recorded by folklorists had average singing voices but this didn't in any way diminish their contribution to the legacy of what we call folk. Pete Seeger reminds us that a mother's lullaby is an important part of folk song.

If you decide that you want to express some musical ideas that you can't find now on an instrument, I suggest you work with a musical notation program and a MIDI keyboard through your computer. This is a logical step-by-step process that allows you to express what you hear inside your head. You might have to learn a little about reading music to work the notational program but with a regular sequencer, you can record notes in slo-mo using step-time recording. Also, with a notational program, you can learn to read music. it may seem overwhelming from the tech side but as you work with it you will
find there are logical steps to help you master it.
