Hanon Exercise No. 47: fingering, tempo and how to practice it

Hanon Exercise No. 47 is part of “The Virtuoso Pianist, Part III (Nos. 44–60): exercices du virtuose” by Charles-Louis Hanon (1819–1900). Main focus: the greatest mechanical challenges. This part contains repeated notes, double notes, scales in thirds and in octaves, and tremolos; the content of each number will be confirmed when it is transcribed. Suggested tempos: start at ♩ = 40 to learn it, practice at ♩ = 50 and work up to the target of ♩ = 60. Difficulty 6/10 (intermediate).

What it trains

The greatest mechanical challenges. This part contains repeated notes, double notes, scales in thirds and in octaves, and tremolos; the content of each number will be confirmed when it is transcribed.
Wrist flexibility and stamina.

How to practice it

Don't start this part until you have mastered the previous two.
In double notes and octaves the wrist stays loose: if it stiffens, stop.
Keep sessions short: these exercises tire the hand a lot.

Tempo ladder: ♩ = 40 → ♩ = 45 → ♩ = 50 → ♩ = 55 → ♩ = 60. Only move up a step once the take comes out clean; in the app, the progressive metronome does it for you.
