Kreutzer etude, viola edition by Consolini, No. 13 Moderato (the violin book's No. 14, a fifth lower): D major, 4/4, quarter = 42 — slow practice (about 55% speed). A play-along for learning it by ear: two bars of clicks, then the whole etude (48 bars) on a sampled solo viola, the score scrolling with a playhead under each note, alto clef with the treble-clef passages as on the printed page. Transcribed bar by bar from the Consolini (Ricordi 1922) page, 2026-10-14.
