Key Notes

- Ground bass was popular in baroque music but repeated chord sequences are still common in today's pop music.

- A ground bass finishes on the dominant or leading note which naturally wants to return to the tonic note to start again.

3 Quick Questions (With Answers)
1. Explain the lesson in two key points.

2. What does this key word mean in this lesson? 'ground bass'
a short, repeated bass line that repeats throughout a piece, forming the structure of the music.
3. Correct this common mistake.
Mistake: A ground bass pattern should finish on the tonic as it 'sounds' finished. Correction: The final bar of the piece should finish on the tonic note, but until that bar, the pattern wants to repeat. Finishing on the dominant or the leading note naturally helps the music return to the first note of the pattern, which should be the tonic.
