Oh, I read that as an independent statement, rather than one qualifying the first.

You read "where the main mode of pitch control is by moving the tuning slide" as an independent statement? What does that mean on its own?

The interrupting parenthetical was so disruptive to the sentence that I thought it said, essentially, "The trombone is the only brass instrument. Parenthetical. The trombone is played by moving the slide."

The learning curve is really not that steep. You pretty quickly learn the landmarks for the 7 positions of the slide.

And micro adjusting positions isn't that hard either. If it doesn't sound right, you adjust. The hard part is figuring out whether to adjust up or down. And that's just experience. My ear still isn't good enough to know whether I'm a little sharp or a little flat. But any note I get wrong at tonight's practice will likely be a note I've hit wrong many times in previous practices.

Programming sequencers visually and with tons of help from the tooling pushes the ear sharpening later in the learning process - and I'm only now starting to realize that maybe making music is about deciding what sounds right... I suppose the trombone and violin's "sink or swim" approach ensures the early acquisition of that skill.

Eh I played trombone in high school and it is very forgiving. You can vibe play a trombone.

I suppose one's ear gets sharpened fast, out of necessity - but I recoil at imagining what the other band members have to get through meanwhile. The process for violin is the same though.

A bad embouchure can put pretty much any brass instrument a full semi-tone out of tune. Trombone is not noticeably different in a beginner band. In my experience it's the beginner French Horn that's usually most out of tune.

But brass being out of tune is not as hard on the ears as the squeaks from a beginner clarinet or saxophone...

Probably the most parent friendly is the flute. It's really hard to get good volume out of a flute so beginners are really quiet and inoffensive. :)

I've been trying to square the physics and my experience. Pedal B flat is the fundamental, low B flat is the 2x, F 3x, mid B flat the 4x, D the 5X, high F is 6X, G half sharp is 7X and high B flat is 8X. The position your music teacher most likely will have told you to adjust is 2nd position - you play it slightly sharper for an A vs the E or C sharp it's also used for. Why is that? It's the major 3rd that has the la…

Most instruments tend to pitch sharp or flat depending on the partial. I don't recall any music teachers giving advice that specific positions should routinely get adjustments, but instead that notes in a particular partial should be adjusted. For example, F above middle C should be flattened when played in 1st position to compensate for 6th partial tending sharp. Or the G in 2nd position above that F needing to be pulled in a bit to compensate for 7th partial tending flat.

Manufacturers have different philosophies around this as well. I have a vintage mid-1960s King 3b whose partials line up differently and require different adjustment from my modern XO 1634... and both of those horns are extremely similar .508 bore tenor trombones.

That advice makes more sense according to my understanding of the physics -- the entire partial might be slightly off and every position in the partial should be adjusted similarly.

The just/equal temperament thing lead me to suspect that it was the 5th partial (a major 3rd partial, the D) that would be the one most likely to be off, but a trombone is neither a perfect cylinder nor a perfect cone so simplified models might be off. The perfect 5th (aka both the F partials) is pretty exact on an ideal model, but a real trombone isn't ideal.

It's not too bad. By the time the rest of the band is also not sounding like a sick animal the trombones have figured it out too. I'm not sure if it's something about the brass tone being more forgiving, the volume of audio coming out of the instrument, the fact that the slide is much physically larger than the violin or viola making it easier to make fine adjustments (and now that I think about it, when I think "the middle orchestra sounds pretty bad" it is mostly the violins and violas, so that's plausible), something else, or some combination of all of the above, but it doesn't take too long (relatively speaking) before the trombones are in tune.

(I played trombone throughout middle and high school.)

But you'd only adjust the position of that A if the band is playing an F major chord. Only then.

The D in 1st position - it varies from horn to horn but more often than not yes it'll be a little flat. If you're playing the D as the third of a Bb major chord, then you're already adjusted, easy. If you need a really in-tune D, either 1) tune the whole horn such that 1st position is not quite "all the way in" so you have some room to sharpen the D, 2) use the D in 4th position instead.

Lowering the thirds of chords when you're playing them is generally not something people worry about until they're serious players. And it's really more of an ear training thing than a neuroticism thing. The exercise is to play a static drone over some speakers (say a D), and then play each note of a D major chord up the range, sliding in an out until you can sort of feel the overtones locking in. On the F# you'll feel the lock-in at a flatter position that F# normally is. And the idea is that this proprioceptive sense of intonation will then carry over to your playing.

I loved playing trombone in school. It's such a simple mechanism, it invites a lot of curiousity, and this piece captures that well. Instruments like piano, violin, and guitar are very visual, essentially wysiwyg. Instruments like saxophones, clarinets, flutes, take a long to mentally map and reason through (this combination of keys achieves note X). Trumpets, and other 3 valve instruments map exactly to trombone positions! Eg. no-valves = 1st position, 1st valve is 3rd position, 1+2 is 4th position. But visually you don't see this, and it doesn't invite the curiousity. Trombone super unique in that you get a little wysiwyg, but you have to square that with embouchure. But learning trombone, and then mapping that knowledge to a euphonium, trumpet, tuba, etc, gives you a knowledge about that instrument (eg ok if note X is 1st valve, and note X+1 is 1+2, then i know adding 2-to-1 adds a half step, because position 3 is a half step from position 4).

If you play piano you should find a tuner who does something better than equal temperament. When you accept that changing keys will change the tone of the song you can get a lot better music. You don't need to go to just temperament (and since you still need octave stretch it wouldn't be ideal anyway - though if you can live with playing music in exactly one key it is nice). I tuned my piano to EBVTIII and I like it.…
