Try to play slower when learning a new piece, especially when playing hands together. Have your eyes on the music and be more careful about looking at where and how the notes are moving.
Let’s clear up everything we play! – play with clarity (no mumbling and cheating through notes) and steady tempo (use your metronome).
Review all technique we’ve been doing (especially the minor scales, Bb and Eb major scales), and arpeggios in all required keys (hands separately)
When memorising: try not to memorise a song by muscle memory, learn all notes, harmony, melody, dynamic changes, and know where exactly everything is on the music
