Chord Explorer in A

In this video

Back from a busy couple of weeks — including Biffy Clyro's biggest ever headline show at Finsbury Park — and tonight we're diving into some songs inspired by that, plus a full exploration of the key of A.

We start with three songs before getting into the theory:

  • Where Is My Mind – The Pixies — the lead part, and why power chord practice is the secret weapon for bar chord struggles

  • Machines – Biffy Clyro — four cowboy chords in G, the "rock G" shape that cleans up the bottom end, and how a rhythm of three over a count of four works

  • Choosing Texas – Ella Langley — a live first-listen jam, working the chords out by ear (capo 1, D minor, F and C), plus tips on playing through mistakes and staying in the groove

Then it's into the key of A explorer, covering the full range from beginner to intermediate:

  • All the ways to play an A chord — three finger, one finger, barre, triad — and when each one is useful

  • The major scale formula in A and how it gives you all the diatonic chords in the key

  • Chord embellishments: major 7, dominant 7, A6, sus2 and sus4

  • Songs touched on include Wild Thing, All Right Now, We Will Rock You and Can't Take My Eyes Off You

  • The Cure deep dive — Boys Don't Cry, In Between Days and Pictures of You, all built from the same diatonic chords running up the A major scale

  • A minor pentatonic — how the key of A opens up into rock and blues territory, with Led Zeppelin and AC/DC riffs to finish

There's also chat about the Brighton Guitar Show, the Dan Hawkins Classic Rock workshop at Water Bear, and a possible upcoming Airbourne interview.
