- Yes — this is a free karaoke slide for "One Time" by Justin Bieber. The lyrics appear on screen a line at a time and each word lights up exactly when it's sung, with a bouncing ball leading you word to word. A backing plays underneath so you can just sing.
- Does it show chords so I can play along on guitar or piano?
- It does — a chord symbol sits on a thin row just above the lyric it changes on, so the same screen doubles as a lyrics-and-chords chart. Guitarists can strum the changes and pianists can comp while singing; the chords are colour-coded and move with the live transpose if you change key.
- Can I change the key of "One Time" to match my voice or capo?
- Yes. The original is in C#, but the live transpose control shifts the whole song up or down semitones until the melody sits in your range (or maps to an easier guitar shape / capo position) — the on-screen chords and the backing move with it.
- Can I slow "One Time" down to learn the words and chords?
- Yes — the tempo control lets you take it as slow as you need while the lyrics still light up in time and the ball keeps you on the beat. Speed it back up once you can sing and play it through.
