Instruments

InstrumentLanesDefault keysHow it plays
Electric Guitar2 lanesF and J (rebindable) · L1 / R1 on controllerSpeed-first: rapid taps for distortion-heavy lead tracks.
Bass Guitar4 lanesX, C, N, M (rebindable) · L2 / L1 / R1 / R2 on controllerLow-end rhythm that holds the tempo under the rest of the band.
Drums4 lanesX, C, N, M (rebindable) · L2 / L1 / R1 / R2 on controllerRelentless beats, cymbal hits and fills as the tempo ramps.
Piano4 lanesX, C, N, M (rebindable) · L2 / L1 / R1 / R2 on controllerTechnical melodic lines with sweeping patterns.

Calibrate first. The moment you pick an instrument up the Calibrate Timing prompt appears — it measures your input latency against a click track, which matters on Bluetooth headphones and TV speakers. Keyboard binds are rebindable in Settings → Rhythm → Keybinds; controller binds are fixed at L1/R1 for two lanes and L2/L1/R1/R2 for four.

Phone music player: 30 tracks

Japanify is the in-game music app — community-picked Japanese and punk tracks, each reviewed by the team before it goes in. This is the list transcribed on the wiki; update #22 added fifteen more songs to the instrument side (American Idiot, Creep, Inferno, Toxicity, Yoru ni Kakeru and others), and the instrument tracklist is not the same as the phone tracklist.

Why you cannot hear other players

Two common causes. If you are wearing headphones connected to the phone music app, your music is private by design — that is the feature, not a bug. If instruments themselves are silent, the music room had a documented break that was fixed in the update #20 sub-patch, so an out-of-date client is worth restarting.
