play note [62] for (0.5) beats

play note [64] for (0.5) beats

play note [65] for (0.5) beats

play note [67] for (1) beat

• Note numbers correspond to MIDI pitches:
• 60 = Middle C
• 62 = D
• 64 = E
• 65 = F
• 67 = G

Example 2: Looping a Melody

Create a looping melody:

when green flag clicked

forever

    play note [60] for (0.5) beats

    play note [62] for (0.5) beats

    play note [64] for (0.5) beats

    play note [65] for (1) beat

end

Example 3: Play a Chord

Use multiple "play note" blocks together for harmony:

when green flag clicked

play note [60] for (1) beat // C

play note [64] for (1) beat // E

play note [67] for (1) beat // G

Example 4: Change Instruments

Use the "set instrument" block to change the sound:

when green flag clicked

set instrument to [Piano v]

play note [60] for (1) beat

set instrument to [Guitar v]

play note [64] for (1) beat

set instrument to [Trumpet v]

play note [67] for (1) beat

Step 4: Advanced Music

1. Use Tempo

Control the speed of your music:

when green flag clicked

set tempo to (120) bpm

play note [60] for (0.5) beats

change tempo by (-10)

play note [62] for (0.5) beats

2. Create a Song Using Variables

Store notes and durations in lists:

when green flag clicked

set [notes v] to [60, 62, 64, 65, 67]

set [durations v] to [0.5, 0.5, 0.5, 1, 1]

repeat (length of [notes v])

    play note (item (repeat counter) of [notes v]) for (item (repeat counter) of [durations v]) beats

end

Step 5: Add Visuals

• Animate sprites to match the music:
• when green flag clicked
• repeat until <not playing>
•     change color effect by (25)
•     wait (0.5) seconds
• end
• Create a light show by changing backdrops:
• when green flag clicked
