The notes inside B, string by string
| 5th string (A) | fret 2: B |
|---|---|
| 4th string (D) | fret 4: F# |
| 3rd string (G) | fret 4: B |
| 2nd string (B) | fret 4: D# |
| 1st string (high E) | fret 2: F# |
From B to Bm only one thing changes: 2nd string (B): fret 4 → fret 3.
Learning B step by step
- Put the shape down slowly and pick each string once to check it rings.
- Lift the hand, then land all fingers together. Repeat ten times.
- Change from B to E and back for a minute; then add F#.
B higher up the neck
This shape has the same notes higher up the neck. Use it when the chord before or after sits nearby.
Making B ring
- Buzzing means the finger is too far from the fret: slide it closer.
- A string is muted? Arch your fingers so they touch only their own string.
- Hurts at first? Normal. Five minutes a day toughens the fingertips in a couple of weeks.
Make B automatic
ChordRunner listens to your guitar: when B appears, strum it and your runner jumps. The game shows the chord symbol only, so you learn to find the shape yourself. MIDI keyboard or microphone, both work.

What notes are in the B guitar chord?
B major has three notes: B, D#, F#. On the guitar some of them are doubled on different strings, so all six (or five) strings sound like one chord.
Which fingers do I use for B?
Index finger: across the strings (barre), fret 2, middle finger: 4th string (D), fret 4, ring finger: 3rd string (G), fret 4, little finger: 2nd string (B), fret 4.
Can I practise B with the microphone?
Yes. ChordRunner hears an acoustic or electric guitar through the microphone, and also a USB MIDI keyboard. It shows the chord symbol B, not the diagram, and checks the notes you strum.
Your instrument is the controller.
ChordRunner is a browser game that teaches piano and guitar chords: a chord appears on screen, you play it on a real instrument, and your runner jumps. MIDI keyboard or microphone, both work.
