Diatonic Chord Scale (open chords) · Exercises

C · Dm · Em · F · G · Am · Bdim

I · ii · iii · IV · V · vi · vii° in the key of C

Nothing here goes past the third fret. Play them up and back down. Most songs you already know are built from four or five of these seven, so they are worth having under your fingers before anything fancier.

Four bars of diatonic chord scale (open chords) in the key of C, written I · ii · iii · IV · V · vi · vii° and played let it ring at around 80 beats per minute. The chord shapes are below, and you can hear the whole thing play — and slow it down — without an account.

What the chords are

This is I · ii · iii · IV · V · vi · vii° in the key of C — the degree of each chord is what makes the progression recognisable in any key, so the same four moves transpose anywhere once you know them by number.

• C I in open position, frets 1 to 3, on 5 strings
• Dm ii in open position, frets 1 to 3, on 4 strings
• Em iii at the 2nd fret, on all six strings
• F IV up at the 1st fret, spanning to the 3rd, on all six strings
• G V in open position, frets 2 to 3, on all six strings
• Am vi in open position, frets 1 to 2, on 5 strings
• Bdim vii° in open position, frets 1 to 2, on 3 strings
