Original eight-bar lead sheet: Open Window
Each listed pitch is a quarter note except rest, a quarter rest. Four events per bar; the chord applies to the whole bar. Register C4 is middle C. The melody is a teaching example, not a familiar song.
| Bar | Chord | Beat 1 | Beat 2 | Beat 3 | Beat 4 |
|---|---|---|---|---|---|
| 1 | C | E4 | G4 | E4 | C4 |
| 2 | Am | E4 | C4 | A3 | rest |
| 3 | F | A3 | C4 | F4 | E4 |
| 4 | G | D4 | B3 | G3 | rest |
| 5 | C | E4 | G4 | C5 | G4 |
| 6 | F | A4 | G4 | F4 | C4 |
| 7 | G | B3 | D4 | F4 | D4 |
| 8 | C | E4 | D4 | C4 | rest |
Four passes through the sheet
First, clap each measure while saying 1–2–3–4. Second, play only the melody (no accompaniment). Third, play only each chord's bass root on beat 1 using C3, A2, F2 and G2. Fourth, combine the melody and bass roots slowly; the left-hand part must remain quieter so the tune is clear.
Decide how much harmony to add
A separate right-hand chord could collide with the written melody. For a first performance, use bass roots only; later, place a soft chord below or between melodic phrases when hand coordination permits. If you replace the precise melody with chord blocks, you have reduced the lead sheet into a chord chart, which is useful but not identical.
Phrase endings and recovery
Treat bar 4 as a small breath and bar 8 as the ending. If you lose your place, restart at bar 5, not necessarily at bar 1. Check chord-symbol reading in the symbol decoder. Learn two-hand chord rhythms before turning this into a dense arrangement.
