I play EC, where most of the music is written in that 2 octave range above middle C. I'd like to transpose some of my familiar dots music down an octive to utilize more of my bass clef on my TED (tenor-extended-down). I have downloaded bassoon lessons to try to help me familiarize myself with that area of fingering. But its not much fun. Then this transposing idea crossed my mind. I am certainly not clever enough to transpose in my mind and work on the base clef fingerings all at the same time; so how about transposition the music scores I am already familiar with for my eyes while I work on the fingering part of the bass clef? A fast scan of internet yeilded "Finale"--some sort of music manipulation program--for $600, I don't think so. I think I have "Audacity" downloaded; does that have such capabilities? And maybe "wavepad"--I never did look at that very closely either. Or are these programs just for manipulating the sound files? Advice from the group please.
