"DUET FOR TWO MATCHED TUBAS"
This piece can be played by any type of two matched tubas , or similar instruments such as euphoniums, barytones,alto-horns, bass-tubas, sousaphones etc...
Section A of the piece is played as written. The requested slaptongue sound should be really loud and percussive.
Section B is played twice: a first time exactly as written (disregarding the numbers on several of the notes), and then a second time by substituting all the pitches with a numerical indication ( +1,+2,+3,+4,+5,+6) by other pitches corresponding to the N-th following harmonic overtone on the valve position for the previously played note ( always F ). As can be seen from the next two examples, worked out for a euphonium, different versions are possible:
Harmonic series on F for the euphonium, when using the (non orthodox) combination of the 2-1/2 + the 1 tone valve:
Example worked out in case the players choose to play F using only the 1-tone valve:
In any version, the series should be rising pitch and both players should use the same valve positions.
In section C players can choose to play either the notes as written, or, if possible, the notes indicates by the numbers above them, transposed one and more octaves downwards.
Section D, the last section, is played as written, forte throughout and with really very strong accents.
This piece can be played as written, it being pretty irrelevant whether the actual pitches sound as written or not, regardless the tuning of the instruments used. Both instruments should be identical and both players should of course read the score the same way.
[duration: approx.3'30" - 4'15"]
