Make a short phrase
Play G – B – D – F♯ – A in quarter notes at 60 bpm. Repeat starting from B, wrapping back to G. Do not speed up until every attack is even.
Hear it in context
Alternate B and F♯ above a sustained G. These are degree 3 and 7. End a four-bar phrase on either one instead of always returning to the root.
Listen for this: G△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
G△9: from a pattern to a musical choice
What gives G△9 its identity?
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 B, and degree 7 is F♯. Play G in the bass and compare these voices individually before combining them.
Turn the arpeggio into a melody
Try B – D – F♯ – G 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 G on string 6, fret 3. The next note B is on string 6, fret 5. 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: G · B · D · F♯ · A. Then play a two-bar phrase from memory and leave two bars of silence.
