Know the finger numbers
On both hands the thumb is 1, index finger 2, middle finger 3, ring finger 4 and little finger 5. For C–D–E–F–G, a simple starting pattern is right hand 1–2–3–4–5 and left hand 5–4–3–2–1. This is not universal fingering for every piece.
Five fingers and an even sound
Play from C to G and back using equal note lengths. Before increasing speed, listen for accidental gaps or rushing. Know which finger comes next rather than reacting at the last moment.
Bring the hands together
Let each hand play the pattern alone first. Then play C–D–E–F–G with both hands travelling in the same direction. The same note names use different finger numbers in the two hands. If timing becomes uneven, choose a slower tempo.
Practise chord changes
Alternate C–E–G and C–F–A in the right hand, holding each for four beats. Notice the common C and where the other notes move. Try inversions such as G–C–E and compare the distance to the next chord.
Separate rhythm from key finding
Count evenly to four. Clap first on every count, then only on counts one and three, while keeping the pulse going. Move the pattern to one key before combining it with a changing sequence of notes.
Bring the skill back into music
Independent exercises develop a skill beyond one piece. A composition lesson prepares you for a specific performance. After practising a skill, find a similar task in a piece you enjoy. Judge the result by control and the sound, as well as speed.
