How I made a Bad Apple remix with zero instruments (it's all code)

No instruments, no singer, no animation software. This Bad Apple!! remix and its shadow-art music video were made entirely in code, in one evening with Claude Code. Here's how it went, including the vocal attempts that went wrong. 0:00 No instruments, no singer 0:15 Synths from a MIDI file 0:33 Mix pass 0:41 Vocal attempts 1-3 1:09 VOICEVOX 1:27 The AI critic 1:44 The music video 2:03 By the numbers Credits Original: Bad Apple!! by ZUN (Touhou Project), arrangement by Alstroemeria Records feat. nomico MIDI: fan transcription by Handhule90 Vocals: VOICEVOX:四国めたん Narration: AI voice (ElevenLabs) Lyrics, remix and video: Parham & Claude #badapple #touhou #claudecode #creativecoding
