Hello!

Thanks for your question. So, do you have all of your music already in a computer program of any sort? The biggest barrier, I think, to you successfully doing this is that it will probably take quite a bit of time. You'd need to input all of the music that you'd like to transpose, and then have the computer transpose it. The inputting can take a while, unless you've got quite a bit of decent equipment, including a piano keyboard that is MIDI capable.

If you DO have an electronic keyboard that is MIDI capable, you'd be able to just "play" the vocal lines that you'd like transposed, and the computer will be able to recognize them from the keyboard. That's a relatively quick way of inputting, and then it would transpose, and you'd be done. If you do NOT have a keyboard that is MIDI capable (ie, able to be hooked up to a computer), you'd need to enter each note individually using your mouse, into the computer program, and this can take a while.

However, there are a variety of programs out there that are available. I'd like to know, first, how you'd like to input the music, and we'll go from there.

Thanks!
