Excellent — that’s a really nice fast arpeggio run exercise! The passage in your screenshot (C♯ major scale/arpeggio pattern moving up and back down) is a classic example of an improvisational run that would appear in a virtuosic passage or embellishment.
Let’s break it down into playable sections with recommended fingerings for both hands, assuming you’re on piano.
This looks like an extended C♯ major arpeggiated run (C♯–D♯–E–F♯–G♯–A♯–B–C♯, etc.), moving across multiple octaves.
Here’s a reliable fingering pattern you can loop as you go up and down:
C♯ – D♯ – G – F♯ – D♯ - D - D# - D - C – B
C - B – C – A – G – A – G - F# - D# - C
B – A - B – A – G – F# – E – D
1 2 3 1 2 3 4 5
Then continue the same pattern in each octave — every time you reach C♯ with your thumb (1), cross under and repeat.
C♯ – B – A♯ – G♯ – F♯ – E – D♯ – C♯
5 4 3 2 1 3 2 1
Use the thumb pivot and crossovers fluidly — think of it like a “rolling” wrist motion, not a rigid scale.
The left hand mirrors the pattern in reverse, using standard arpeggio technique.
C♯ – D♯ – E – F♯ – G♯ – A♯ – B – C♯
5 4 3 2 1 3 2 1
C♯ – B – A♯ – G♯ – F♯ – E – D♯ – C♯
1 2 3 1 2 3 4 5
Keep the wrist relaxed — your thumb crossings should feel like a smooth “passing under,” not a jab.
Think in groups of four or five notes to maintain phrasing and balance.
Use arm motion to travel across octaves rather than stretching fingers excessively.
Practice hands separately first, then hands together slowly with even tone.
Pedal lightly (half pedal) to blend the sound if it’s meant to be a flowing improvisation.
Once you’re comfortable, try:
Using the same fingering pattern but changing keys (D major, E major, etc.).
Turning the run into broken chord sequences (e.g., 1–3–5–8 of each chord).
Adding dynamics — crescendo up, decrescendo down.
Experimenting with swing or rubato for expressive runs in jazz/blues improvisation.
