Hanon — Part I
Charles-Louis Hanon's The Virtuoso Pianist (1873) opens with twenty preparatory exercises that build finger independence and strength — especially the weak 4th and 5th — and bring the left hand up to the level of the right. Here all twenty are transcribed to notation you can read and hear.
Read & hear — one exercise at a time
Pick a number, press Play, and read a beat ahead — right hand in gold, left hand in blue. A highlight band sweeps the staff while the keyboard lights up. Tempo follows the metronome bar (start slow).
Transposing keeps the pattern near middle C and draws the matching key signature — great for taking one exercise through every key, as Hanon intended.
Notes parsed from the Mutopia Project engraving (typeset by Javier Ruiz-Alma, CC BY-SA); fingerings are Hanon's where he marked them. Music is public domain (Hanon, 1873).
All 60 exercises & the original score
These twenty are just Part I. To read the full engraved score for all three parts — Part II (scales, arpeggios, broken chords) and Part III (octaves, repeated notes, trills, tremolos) included — use the score reader on the Sight-reading page, where the complete PDF is embedded with a Part I / II / III selector and downloads.
