Practice Tips
- Play Bb with just the right hand, one octave, very slowly — notice there are no half steps, giving it that open, bright quality.
- Memorise the 5-note shape: Bb–C–D–F–G–Bb. Know it before focusing on fingering.
- Loop the scale — go up one octave and immediately back down without stopping, keeping steady pulse.
- Improvise using just 3-4 notes at a time over a simple A#/Bb Major chord, leaving space between phrases.
- Practice in contrary motion with both hands moving outward from the centre simultaneously.
- Connect to the chord: play A#/Bb Major chord first, then the pentatonic scale above it to hear how they fit.
