Practice Routine
Start by playing the D# Diminished Seventh arpeggio ascending and descending at 60 BPM, one note per beat, using a metronome. Once even and confident, play it in eighth notes, then triplets, keeping each note articulate. Spend at least 5 minutes daily on this before moving to musical application.
Ukulele Tips
