Where can I find a piccolo trumpet fingering chart?
It fingers just like a regular Bb trumpet--only an octave lower. A 4th line "D" is fingered 1-3, 4th space "E", 1-2. To make it easier to read picc. parts they are very often written an octave lower than they are actually sounded. The 4th valve is roughly equivalent to the 1-3 combination. Basically it is used to correct intonation problems and to be able to play notes lower than the 1st space "F#". The 1st space "F#" can be played 2-4, 1st space "F" is played 1-4, 1st line "E" is played 1-2-4, so on so forth. Not really something you can learn without actually having a horn in your hands.
