Choir Conductor — free browser game

You're the choir conductor: from left to right you have four lanes — Soprano (A/1, pink), Alto (S/2, yellow), Tenor (D/3, green) and Bass (F/4, blue); you have to catch the coloured notes falling from the top the moment they touch the white hit-zone line near the bottom of the stage by pressing that lane's key (A/S/D/F or 1-4 on the keyboard, or the four touch buttons at the bottom on mobile). Hit dead centre and you earn a BRAVO worth 100 points, be slightly off for a good 60, and just inside the edge for 30 points; consecutive correct hits build the combo counter, and every 5 combos both speeds up your note-fall tempo and adds extra bonus points per hit. Pressing a lane's key with no note there, or letting a note slip past the zone, counts as being out of tune, resets your combo and raises the miss counter — 5 misses and the concert is over. Start/restart with Space or Enter, reset with R; your highest score is saved in localStorage. Tip: lock your eyes onto the hit-zone line rather than any single note and keep your fingers resting on the four keys; since the tempo rises as your combo grows, steady taps that follow the rhythm pull your perfect rate up more than rushed hits do.
