Chord Battle: Duels, Races and Live Rounds
A chord battle is chord practice turned into a race: two or more players get the same chords on the same clock, and the fastest, cleanest hands win the round. ChordRunner runs chord battles in the browser where you play on a real instrument, so a battle rewards true recall rather than quick clicking, and every round doubles as a workout.

Alone, a wrong or late chord costs you nothing. In a battle it costs you a place on the scoreboard, and that tiny stake changes everything. Suddenly you cannot ease off on the chord you secretly dread, because the clock and your rival do not wait. That is the whole trick: a battle manufactures the exact pressure a real performance brings, where the next chord lands whether your hand is ready or not.
It is also just more fun than a metronome, which is the honest reason it works. People repeat what they enjoy, and a battle you lost by two chords is a battle you immediately want to run again, racking up reps that a solo drill could never talk you into.

Duels, races and endless rounds
One-on-one, or a whole pack
A battle scales to whoever shows up. A session with just two players is a clean duel, same chords, one clock, one winner, and you can set that up on purpose by inviting a specific friend to a private room. Fill the room instead and it becomes a pack race up a shared leaderboard. Either way every round starts everyone from zero, so it is a fair fight, not a defence of some lifetime score.
Rounds that end honestly
Endless battles run in two-minute rounds; a host who sets a length gets a match clamped to a fair two-to-five-minute window. In modes with monsters or bosses, falling too far behind can knock you out before the timer, so a round resolves on real performance rather than dragging on. When the clock stops, final rankings appear and you go again.
From battle to better playing
The reason a chord battle beats a quiz is that it trains the skill you actually use: forming the right shape, in time, without stalling. The chords you fumble in a round are not a failure, they are a free, specific practice list. Take them into solo chord training or a timed chord challenge, drill them until they stop being special, then come back and collect the win. For every way to play against or alongside others, see real-time multiplayer music learning.

Common questions
What is a chord battle?
A chord battle is a head-to-head race where players are given the same chords on the same clock, and whoever lands them faster and more accurately climbs the live scoreboard. In ChordRunner you play the chords on a real instrument, so it rewards genuine recall, not fast clicking.
Can I duel just one other player?
Yes. A session with two players is effectively a duel: same chords, one clock, one winner per round. You can invite a specific friend to a private room for a one-on-one, or join a public session to battle whoever is there.
How long is a chord battle round?
Endless battles run in two-minute rounds. When the host sets a length, the match is clamped to a fair two-to-five-minute window. In modes with monsters or bosses, falling too far behind can eliminate you before the timer, so a round is never dragged out artificially.
Do chord battles actually improve my playing?
Yes, because they train recall under pressure, the exact skill a real song demands when the next chord arrives whether you are ready or not. A few competitive rounds pack in many honest reps, and the ones you fumble become an obvious, specific practice list.
