I’m trying to learn to play piano and, as a former trumpet player, my right hand is doing fine but my left hand is struggling just because my brain hasn’t “learned” to read bass clef yet.
So, instead of spending time learning bass clef notes, I’m instead trying to understand why music is written in a staff using a bass clef at all. I understand that the bass clef denotes notes that are lower in pitch, notes that, if you were to put them on a treble clef, would be so far below the five lines of the staff that it would be incredibly inconvenient to play them.
However, why not just write the notes in treble clef with the understanding that they are one octave lower? (Or two octaves, or whatever they are.) If you tell me to play a C with my left hand, I can do it in any octave on a piano.
(I suppose the argument could be made to write everything in treble clef for those that learned bass clef notes first - I guess my question is more about why have different clefs at all.)
