A minor arpeggio: piano fingering and how to practice it

A minor arpeggio is part of “The Virtuoso Pianist, Part II (Nos. 21–43): exercices transcendants” by Charles-Louis Hanon (1819–1900). Main focus: root-position A minor triad arpeggio over 4 octaves. In our transcription it is in A minor, in 4/4 time, and 2 bars long. Suggested tempos: start at ♩ = 46 to learn it, practice at ♩ = 72 and work up to the target of ♩ = 92. Difficulty 4/10 (intermediate).

The pattern and its fingering

Root-position A minor triad arpeggio over 4 octaves.

How to practice it

Open the hand from the palm, not by stretching the fingers: the arm carries the hand from one position to the next.
The thumb crossing is longer than in scales: prepare it early and without raising the elbow.
First practice the blocked chord in each octave to memorize the position.

Tempo ladder: ♩ = 46 → ♩ = 59 → ♩ = 72 → ♩ = 82 → ♩ = 92. Only move up a step once the take comes out clean; in the app, the progressive metronome does it for you.
