Practice Routine
Start by playing the F# Altered 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.
Bass Tips
On bass, use the F# Altered arpeggio as the skeleton for your bass lines. Target the root on beat 1, then use the other tones (A#, E, G) on weaker beats to create movement while keeping the harmonic foundation solid.
