PLAYER app breaks songs down into chords and keys
Gloria Chan
For the musical souls among us, singing along to a song but not being able to figure out the chords can be a drag. Musician, engineer and app-maker Johnny Quattro (a rocker's name if ever there was one) knows that feeling all too well - or, rather, he used to.

Launched this month, the app has already scooped the Editor's Choice award in the Apple App Store. Quattro believes PLAYER is popular because it allows anyone - from beginners to expert songwriters - to play along to the songs on their playlist.
"When I was 13, I learned guitar by playing and pausing vinyl records over and over again," Quattro says.
"That's a common way to learn music in the West, so I decided to combine my music-learning experience with smart-phone technology."
PLAYER is connected to a user's iTunes library. Once you press the "learn" button next to a song, the app analyses it and shows sheet music for the guitar, ukulele or piano. You can then play along either in real time, three-quarter time or at half-speed.
