the ground bass

• the ground bass is a 3 bar loop
• it consists entirely of quaver rhythms
• it has a rising pattern
• the first 4 sets of 4 quavers use an ascending sequence, starting one note higher each time
• at the end of the ground bass there is a fall of an octave
• it uses intervals of semitones
• after 4 and a half repeats of the ground bass it begins to modulate into different keys
• in the final section A section (bar 29) it returns to the repeating pattern from the start of the piece
