HOWCURIO ORIGINAL SONG MAKER STARTER Open https://musiclab.chromeexperiments.com/Song-Maker/ SETTINGS Length: 2 bars Beats per bar: 4 Split beats into: 2 Scale: Major Start on: Middle C Range: 2 octave Tempo: 120 Melody instrument: Marimba Confirm Settings with the checkmark. PLACE FOUR MELODY NOTES Count columns from the left, starting at 1. Count colored melody rows upward from the bottom, starting at 1. Do not count the two percussion-dot rows beneath the melody. Column 1, bottom-up row 1: C Column 5, bottom-up row 3: E Column 9, bottom-up row 5: G Column 13, bottom-up row 3: E There are 16 time columns: 2 bars x 4 beats x 2 divisions. The four notes begin two beats apart. Leave the other cells empty. Play starts the loop. Stop ends playback. Undo removes the last edit. VARIATION TO TRY Replace the final E at column 13 with bottom-row C at the same column. This variation is a suggestion; only the four-note C E G E pattern above was entered in the recorded browser trial on October 16, 2026. This text is a manual placement recipe, not an importable Song Maker file. No account, microphone, MIDI keyboard, download or shared-song link was used in the recorded exercise. Browser playback controls were observed; physical speaker output and subjective sound quality were not assessed. Original note pattern and instructions by HowCurio, 2026.
