Locate E, B on white keys and G♯, D♯, F♯ on black keys. Try each hand separately before playing together; choose a fingering that keeps the wrist relaxed, without stretching between notes.
Play E – G♯ – B – D♯ – F♯ in quarter notes at 60 bpm. Repeat starting from G♯, wrapping back to E. Do not speed up until every attack is even.
Alternate G♯ and D♯ above a sustained E. These are degree 3 and 7. End a four-bar phrase on either one instead of always returning to the root.
Listen for this: E△9 has the colour “wide, luminous”. Name the degrees as you play, so you can recognize the sound in another key rather than remembering only a shape.
Understand the sound
The ninth adds colour above a major-seventh foundation. Separate the upper voice from the bass and compare close and open spacing.
Here the third is G♯, and degree 7 is D♯. Play E in the bass and compare these voices individually before combining them.
Try G♯ – B – D♯ – E as quarter notes, then repeat the first note and omit the last. The second phrase uses the same harmony with a different shape.
Separate the bass from the upper notes. If the low register sounds muddy, move the upper voices up an octave before adding more notes.
The black-key pitches in this collection are G♯, D♯, F♯. Use the groups of two and three black keys to orient yourself. Play E and G♯ with each hand separately before combining the hands.
Before moving on, close the diagram and name the notes: E · G♯ · B · D♯ · F♯. Then play a two-bar phrase from memory and leave two bars of silence.

E Major (E F♯ G♯ A B C♯ D♯) — the arpeggio is the skeleton of that scale, so practise them together.
Play E – G♯ – B – D♯ – F♯ ascending from E, then descend; then start from each chord tone in turn (inversions) so your hand knows the shape from any note.
