Find A on string 6 at fret 5. Play string 6, fret 5; string 6, fret 8; string 5, fret 7; string 5, fret 9; string 4, fret 7. Use a relaxed position and release pressure between repetitions. String 1 is high E.
Play A – C – E – F♯ in quarter notes at 60 bpm. Repeat starting from C, wrapping back to A. Do not speed up until every attack is even.
Alternate C and F♯ above a sustained A. These are degree ♭3 and 6. End a four-bar phrase on either one instead of always returning to the root.
Listen for this: Am6 has the colour “minor but bright”. Name the degrees as you play, so you can recognize the sound in another key rather than remembering only a shape.
Understand the sound
This chord has a minor third and a natural sixth. The sixth is not a flat sixth; compare those notes over the same minor triad.
Here the third is C, and degree 6 is F♯. Play A in the bass and compare these voices individually before combining them.
Try C – E – F♯ – A 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.
Start with A on string 6, fret 5. The next note C is on string 6, fret 8. 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: A · C · E · F♯. Then play a two-bar phrase from memory and leave two bars of silence.

A – C – E – F♯. As chord tones: 1 ♭3 5 6. Played one after another instead of together, that is the arpeggio.
Am6 is a minor tonic with a Dorian colour, or a rootless 9th of a dominant a fourth below. Its character is minor but bright.
A Melodic minor (A B C D E F♯ G♯) — the arpeggio is the skeleton of that scale, so practise them together.
Start on the root A on the low E string at fret 5 and play E-string fret 5, E-string fret 8, A-string fret 7, A-string fret 9, D-string fret 7. Then play it descending, then in eighth notes with a metronome, then use it in a short phrase over a suitable chord.
