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.
