In this lesson, you’ll learn to play in waltz time (3/4) and the key of B, using the Neil Young song “Only Love Can Break Your Heart.” Waltz time has three beats per measure, instead of four, and often the bass just plays one note on the downbeat. In the key of B, the I, IV, and V chords are B, E, and F#, and “Only Love Can Break Your Heart” also uses the ii and iii chords—minor chords on the second and third steps of the scale, which, in B, are C#m and D#m. Zoe starts by showing you the bass line she plays on the first half of the song (the verse), beginning with a walk up from F# to B. Then she shows you the bass line on the chorus, which descends through E, D#m, C#m, and F# chords.
