Make a short phrase
Play E – G – B♭ – D♭ in quarter notes at 60 bpm. Repeat starting from G, wrapping back to E. Do not speed up until every attack is even.
Hear it in context
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°7 has the colour “symmetrical, restless”. Name the degrees as you play, so you can recognize the sound in another key rather than remembering only a shape.
Understand the sound
E°7: from a pattern to a musical choice
What gives E°7 its identity?
Successive chord tones are separated by minor thirds. The seventh is a diminished seventh, not a major sixth in the chord’s theoretical spelling, even when they share a piano key.
Here the third is G, and degree 𝄫7 is D♭. Play E in the bass and compare these voices individually before combining them.
Turn the arpeggio into a melody
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.
Sound the strings separately before playing them together. If a note is muted, adjust the finger angle instead of squeezing harder.
Your guitar checkpoint
Start with E on string 5, fret 7. The next note G is on string 5, fret 10. Name both notes aloud before playing, then find the same two pitches in another octave.
Before moving on, close the diagram and name the notes: E · G · B♭ · D♭. Then play a two-bar phrase from memory and leave two bars of silence.
