The matching file likely isn’t present, or the name doesn’t match exactly. Filenames can be case-sensitive on some hosts.
Use the “word” style shown in the examples: Fsharp4.wav, Bflat3.wav. Make sure your folder matches the AUDIO_BASE_PATH in the page.
Difficulty comes from rhythm (8ths), note patterns (sequences), and larger interval jumps—not just the key.
