So, if you play a C on a clarinet, it's really a B-flat on a piano? Please explain pitch, so my brain will stop twitching. (This question comes to you from a former trombone player, which is not a transposing instrument.)Ok, for the cessation of brain twitching, because transposing instruments can be, er, a mental pain at the least.
It's all about the
name of the pitch. It was decided that on a clarinet that particular size, if you hold the thumb, 1st, 2nd and 3rd fingers down on the left hand and play, they're gonna call that note 'C'. It just so happens it sounds as a B-flat on the piano. Why do that? Some of it has to do with similarity of instrument fingerings more valued than pitch names. Take that clarinet, and add the register key, and now you'll be playing a high G. Take a flute, and finger thumb, 1st, 2nd, and 3rd finger on the left hand, and you'll play another G. Same thing on all saxophones. You can take the knowledge of one instrument and transfer it to another easily without having to relearn note-to-fingering relationships. Only the sounding pitch will change. (The flute G will of course sound as G. The clarinet G will sound as F, as will the tenor sax. And the alto and bari saxes' G will sound as B-flat.)
Now, to something closer to your area of expertise- low brass. You play trombone, a non-transposing instrument as you said. You had to deal with a butt load of flats, along with the flutes, and any oboes and bassoons. Were there baritones in your band? If so, did they read bass or treble clef? Because if they read bass clef (as they should) then they read the same music as you, keyed in concert pitch. The lowest open tone for them was a B-flat, just like your lowest 1st position. However, if they were baritones in treble clef, then they're written like trumpets, only an octave lower, and their lowest open tone would be a C. Why?? Because band directors need to offer bribes to get more low brass, and if a kid who's not gonna rock anyone's world on trumpet could be convinced to switch to baritone and help the low end of the works, then that's helping everyone. And one way to do this is tell 'em, "The fingerings and notes are the same, it's just a bigger horn." And it is! But, if they show promise, it's better to teach them bass clef and transition them into the world of concert pitch.
Does that help at all? Really, it breaks down to what names to give pitches with various conditions, like fingering similarities and horn size.

Who was the principal manufacturer of Ophicleide valve oil?I worry about this guy...
*sigh* Well, to begin, the ophicleide is a
keyed instrument, not a valved instrument. So, valve oil would not be appropriate for such a purpose. And damned if I could find even a hint of any oil manufacturer for Adolphe Sax as he was fixing ophecleides and perfecting the bass clarinet. Sorry, that's all I got.
Ok, I'm on the current last question, from
tangerinpenguin:
Question for the trumpet player:
On your typical C trumpet, moving up the lowest C major octave in normal use (the one beginning one ledger below the staff) the C, G and C (root, fifth and octave, respectively) can be played with no valves pressed. In the octave above that, you get the same fingerings for those notes, but you add an E (third) that can be played open.
The same pattern occurs in the baritone horn and the tuba, for their appropriate ranges.
Does this pattern (of an increasing number of notes within the octave that can be played with no valves) continue as the octaves go up, and if so, how high would you have to go before you could play a full C major scale with no valves (in principle, at least)?Yes, the pattern continues, and the best example you can hear this is on the French Horn. Because the horn has been blessed (or cursed) with a trombone-length tube to be played using a trumpet-sized mouthpiece, you get interesting properties. Your lowest tones are difficult to produce, but it doesn't take long to work up the notes before you're an octave or two above where you'd be comparatively on the trumpet or trombone.
It's all due to the harmonic series, based on ratios. There is a fundamental tone on all brass instruments, but due to mouthpiece construction it cannot be played reliably on
any of them. The next open tone is an octave above that (2:1 relationship in tone frequency), which I'll call the low C since I
am a trumpet player. The next open tone is a fifth above low C, G (3:2 relationship in frequency). Here's a chart so I don't ramble on for 14 more lines:
Note....................
Frequency ratio to previous noteLow-low C (fundamental)...........1:1 (it's the lowest note possible)
Low C (ledger line below staff)...2:1 (an octave higher, twice the frequency)
Middle G .........................3:2 (3*G's frequency = 2*C's frequency)
C (in the staff, 3rd space).......4:3 (follow the pattern)
E (4th space).....................5:4
G (on top of staff)...............6:5
B-flat (out-of-tune, but there)...7:6
C (2 ledger lines above staff)....8:7 (high C is a little more than a whole step above the 'false' B-flat)
D (a step above high C)...........9:8
E (a step above D)................10:9 (this is where it starts to look promising
F# (repeat).......................11:10 (this is where it blows chunks)
So, once you get *three octaves* above the fundamental (or two above the lowest playable open note) you can begin to play melodies like "Three Blind Mice", but no major scale. The reason is that it takes more steps on the harmonic series before you get a true half step, and then you're so high that you're either shredding your lip muscles or you're Arturo Santobal. Now, on the French horn, these notes are much more accessible, but it takes painfully accurate precision to play a scale, all open, in tune, so it's almost as equally as hard. But I would say that you need to be four octaves above the fundamental pitch of the instrument, or three octaves above the lowest playable in-tune note.
