Bassline to a chord chart
Write an 8-bar bassline for this chord chart that follows every rule below. Bass only: no drums or other instruments.
- 100 BPM, 4/4, 8 bars (19.2 seconds), one chord per bar: | Am | F | C | G | Am | Dm | E | Am |.
- Start a note exactly on beat 1 of every bar, and that note must be the root of the bar's chord.
- Use only chord tones, or passing tones: a non-chord note reached by a step (1 or 2 semitones) from the note before and left by a step to the note after.
full spec (7 points)
- Stay between E1 and G2 inclusive.
- Approach each new chord by step: the last note before each bar line is 1 or 2 semitones from the next bar's first note.
- One note at a time (monophonic): no overlapping notes. Use a single pitched instrument and label it bass.
- Every note you trigger must be audible.
