Find B on string 6 at fret 7. Play string 6, fret 7; string 6, fret 10; string 5, fret 9; string 4, fret 7; string 4, fret 9. Use a relaxed position and release pressure between repetitions. String 1 is high E.
Play B – D – F♯ – A in quarter notes at 60 bpm. Repeat starting from D, wrapping back to B. Do not speed up until every attack is even.
Alternate D and A above a sustained B. These are degree ♭3 and ♭7. End a four-bar phrase on either one instead of always returning to the root.
Listen for this: Bm7 has the colour “soft, warm, unresolved”. 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 minor third supplies the minor identity and the flat seventh keeps the sound open. Preserve both when reducing the chord to a small voicing.
Here the third is D, and degree ♭7 is A. Play B in the bass and compare these voices individually before combining them.
Try D – F♯ – A – B 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 B on string 6, fret 7. The next note D is on string 6, 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: B · D · F♯ · A. Then play a two-bar phrase from memory and leave two bars of silence.

B – D – F♯ – A. As chord tones: 1 ♭3 5 ♭7. Played one after another instead of together, that is the arpeggio.
Bm7 is the ii chord in a major ii–V–I, and minor-key tonics. Its character is soft, warm, unresolved.
B Dorian (B C♯ D E F♯ G♯ A) — the arpeggio is the skeleton of that scale, so practise them together.
Start on the root B on the low E string at fret 7 and play E-string fret 7, E-string fret 10, A-string fret 9, D-string fret 7, D-string fret 9. Then play it descending, then in eighth notes with a metronome, then use it in a short phrase over a suitable chord.
