Learning Abm step by step

  1. Put the shape down slowly and pick each string once to check it rings.
  2. Take the hand off and put the whole shape back at once, ten times in a row.
  3. Switch between Abm and Cb for one minute, then try Dbm.

Play Abm with these chords

These chords share notes with Abm and sound right next to it. Practise switching between them.

If Abm does not sound clean

  • 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.
  • Sore fingertips are normal at the start; short daily practice fixes it.

Practise Abm with the microphone

Strum Abm near the microphone when it appears and the game hears it. On screen you see the symbol, not the diagram: that is how the shape sticks. MIDI keyboard or microphone, both work.

Common questions

Is Abm easy on guitar?

It is a barre chord at fret 4, so it takes a little more strength at first. Start slowly, check that every string rings, then practise switching to Cb.

Which fingers do I use for Abm?

Index finger: across the strings (barre), fret 4, ring finger: 5th string (A), fret 6, little finger: 4th string (D), fret 6.

Can I practise Abm 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 Abm, 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.
