How to play Couple Skate: key, chords and progression
To play Couple Skate by Ollie Byrd, think in D major (two sharps: F♯, C♯). It takes 4 chords: D, G, Bm and E.
Listen for D – G – Bm – D (I – IV – vi – I in D major): the song comes back to it again and again. In solfa, that is doh – fah – lah – doh. Once these 4 changes are comfortable, most of the song is done.
Easier on guitar: put a capo on the 7th fret and play the shapes G, C, Em, A (100% of the chords become easy open shapes, against 75% without a capo). It sounds exactly the same.
