As with No. 13 and No. 21 (0r No. 22, depending on the edition), this study is an exercise in consistency and flexibility. Slurring through this etude slowly can help with centering each note. Suggested tempo range in my edition is quarter note=104-160, although 144 seemed fast enough to me for Allegro Moderato. If you’ve seen the last several videos in this series you’ll notice that I’m sitting in a different position for this recording. Normally my bell points towards the curtains in my practice room at home, but this time I thought it would be interesting to face a different direction. The sound is ok with this setup, but the flat, hard surface directly behind the bell created some undesirable echoes.
