To learn Petula Clark - (Mono Version) Chariot chords, these are the chords to practise in sequence: Db, E, D, E, D, A, D, E, Abm and B. A good strategy is to initiate at 59 BPM and then accelerate to the track's regular speed of 119 BPM. Adjust the capo based on your vocal range and chord preference, keeping the song's key of Db Minor in mind.
