![]() See the ETSP Chart for the Bb trombone (without attachment), below. A more precise graphical portrayal of Equitempered Tones (vertical axis) versus Slide Position extension (horizontal axis) results in a good representation of where to find equitempered tones-the ETSP Chart. So all these tones require slide-position adjustment for equitemperament, as shown precisely in Mark McDunn’s diagram.Īnders Larson’s Digitaltrombone chart (from the second to the twelfth harmonic) is qualitatively correct, but quantitatively fairly “approximate”. essentially half-way between reference positions) the thirteenth is 41¢ sharp the fifteenth is 12¢ flat (2¢ sharper than the fifth harmonic or 14¢ flatter than the third). twice as sharp as the third) the eleventh and twenty-second are 49¢ flat (i.e. In these fixed reference positions, compared to their nearest (in frequency) equitempered tones, the third, sixth, twelfth, and twenty-fourth natural harmonics are all 2¢ sharp the fifth, tenth, and twentieth are all 14¢ flat the seventh and fourteenth are 31¢ flat the ninth and eighteenth are 4¢ sharp (i.e. The reference positions correspond to fixed positions for natural harmonics one, two, four, eight, and sixteen. ![]() We must add seven new (different) positions for each odd harmonic above that. Mark McDunn’s “The 51 Positions” chart goes from the first natural harmonic (pedal) up to the sixteenth harmonic. When they get note-wise close there is just not enough room to display everything on paper, but the mind's eye can zoom in on the detail to follow the paths. And most charts do not well handle the compression of partials as they go up. The ear can then recognize in aural context there are position paths available for play, not just notes.Īnyway, this chart does not support that kind of thing. So melody becomes a path of connected positions in the chart. (Lower in his visual model is higher in pitch-don't get that part.)Īnyway, the internal visual model allows one to think visually about lines, and Greg does that in his chart. The best representation of such chart I have seen is in Greg Waits' book, but for some reason his internal model is upside down relative to mine. What I mean by internal model is an internal visualization of the position chart. I was kind of inspired by a friend, who was able to learn corresponding C melody fingering on a Bb trumpet.This chart does not align with my internal model, though it seems pretty accurate for someone with a horn that behaves in that way on his own face. The horn needs some work and before I send it out for repair, I wanted to determine if I could play from where I am, musically. ![]() Ive always fantasized playing a verse or 2 with the trombone. I still perform, vocals and now, keytar with tracks. ![]() Over the years, Ive collected tons on music, fake books etc. But, shortly after, I joined a combo with accordion and vocals and the trombone was put in storage till now. One of the band members offered one of his horns - a Holten Paul Whiteman model tenor horn - for $50.00, I paid him $5.00 a week. After high school, I joined a community band and borrowed the instrument belonging to the high school and got caught. I learned very mechanically and we were able to pull it off for 3 years. Reinhardt who attempted to turn a couple of guitar and accordion players into trombonists almost instantly. Our principle brought in the much revered Donald S. Long story back in the mid 50s, (yeah, Im old) I was volunteered to play trombone in our new high school band.
