Actually, I thought that was NOT true! I might be mistaken (the music might have been written with accidentals but no key signature - certainly it confused the hell out of me!) but I'm sure I've had some American band music put in front of me that (a) was in bass clef and (b) was transposed in Bf! > >> Okay.

A "C" flute may have a C foot or > a B foot. An Eb baritone saxophone may go to low Bb or low A, > I thin we've had this discussion here before ... but as you have correctly said I'm a trombone player, not woodwind. The lowest note on a brass instrument has a half-wavelength equal to the length of the instrument. I get the impression that the lowest note on many woodwind instruments has a quarter-wavelength equal to the length of the instrument. At the end of the day, I was trying to get across the fact that the note depends on the length of the instrument - hence "determined by the length" rather than explicitly drawing any relationship. So that explains your point about an Eb sax going to Bb or A - the lowest note on a woodwind is typically a harmonic of the fundamental rather than an octave of it (that funny 1/4 or 3/4 relationship). I don't know what you mean by a "foot". Is that where you have eg a C flute, and by replacing the foot with a longer one you convert it to a B instrument? Like you change the pitch of a horn by changing its crook? If that's the case, my definition still holds - changing the foot changes the length, and therefore changes the fundamental. I'd call a flute like that a C/B flute, just like my trombone is a Bf/F - using the trigger adds extra tubing to change the fundamental (though like so much with instruments, I'd call that on the trombone a cheat - you don't call a four-valve euph a Bf/F!). The thing I really wanted to get away from is the implication that the instrument is named after the transposing note, whereas reality is that the transposing note is chosen based on the fundamentals of the instrument - as written it implies the effect is responsible for the cause ... > >> Except for those whose notated and sounding pitches >> differ by one or more octaves (to reduce the number of ledger lines >> needed), most such instruments are identified by the letter name of the >> pitch class of their fundamental.

The trombone (along with the violin) is one of the oldest modern instruments in its current form - the basic design hasn't changed since the sackbut of the 1500s. And unlike the horn or trumpet of that era (which achieved chromaticity by changing a crook) the trombone was fully chromatic in its basic configuration, so it was written in standard pitch while the other instruments were written in what I call tablature - where the note indicates fingering not pitch - ie a typical modern transposed part :-) Then from wikipedia ... About 1900, the decision was made, in the British brass band world, to transpose the tenor trombone just like all the other brass instruments because tenor clef concert and treble clef Bf just happened (accidentals apart) to place the same note in the same place on the staff. This made it easier for arrangers, and for players switching between the trombone and other instruments. The true bass trombone - a G instrument, still popular at the time - stayed notated in bass clef. (The modern bass trombone is actually a variant of the Bf tenor - the German "tenorbass" instrument.) My experience as a young trombone player probably isn't atypical - I learnt my music craft on the cornet (Bf treble clef) in a brass band, switched to the trombone (again Bf treble clef), switched to playing in orchestras and had to learn bass clef concert, expanded my range and learnt tenor clef concert (as I said above, dead easy once you remembered the accidentals!), and then playing with a music ensemble found myself learning treble clef concert as well! The one typical trombone clef I can't do is alto. I now prefer playing in bass clef, and when playing in a concert band and I have a choice of clef, that's what I choose. When playing in a brass band, I play treble just like everyone else ... :-) Cheers, Wol _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
