The piece
This English tune was already circulating in the sixteenth century, and Shakespeare mentions it in The Merry Wives of Windsor. The idea that Henry VIII wrote it is a legend with no established basis. Its melody in triple time, set in A minor here, has the air of a lament. Noctave's version, based on the common form of the tune, puts the melody low in the left hand, under paired notes held by the right.
A long-short rhythm runs through it: a dotted quarter, an eighth, then a quarter, like a dance with a slight limp. Keep the eighth short, or the lilt goes flat. The left hand reaches down to the low E and meets two accidentals worth spotting on the staff in advance: G-sharp, which returns at almost every cadence, and F-sharp, in the lines that step down from G. In the right hand, thirds and fourths last the full bar, so place them gently. If reading the bass clef slows you down, wait mode lets each low note wait for you.
