#2A: Time: 1-2 minutes. Insert a mute (normal, non-transposing); this eliminates or at least lessens your subconscious desire or need to make ‘a good sound’ initially. Play several gentle, slurred middle-register chromatic scales over a range of, firstly an octave, then a twelfth. Start around A or G below middle C. NB Remember to BREATHE and to push air THROUGH the horn, not ‘at’ it. NNB No tonguing yet. #2B: Time: 1-2 minutes. Remove the mute and repeat the above. Don’t worry at this stage about getting a ‘pure’ or ‘clean’ tone quality. Exercises #2A to #2D are primarily ‘callisthenic’ procedures rather than musical statements or performances! (Play unmuted from now on) #2C: Time: 3-4 minutes. a) Play slurred sections of the harmonic series (stay on one valve combination at a time, of course) working outwards from the middle register. Start on the F-side (if you have one) and proceed to the Bb side by alternately lengthening and shortening the valve combinations Music example #2Ca: b) Gradually add on more notes, including the out-of-tune notes of the harmonic series e.g. Harmonics 7 (quite flat) and 11 (quite sharp) as well. Play as high as top-space G, and maybe the G# and the A above. Music example #2Cb: #2D: Time: 2 minutes: Repeat the 2nd part of #2C but gradually introduce tongued groups of notes; try to play higher, up to Bb, B natural and C if possible. Music example #2D: Rest for 30 seconds -one minute
