## What is Hinge Harp?

Hinge Harp is a pocket instrument designed for foldable iPhone. Fold it like a laptop, strum across the crease, and play chords on the pads below. Every note fits the key, so there are no wrong ones.

FOLD IT AND PLAY
On a foldable iPhone, the strum strip sits right in the fold. Hold a chord on the pads and run a finger across the crease to strum it. Stand the phone up the other way and the strip stands upright between your hands.

ALWAYS IN KEY
Pick a root and a scale: major and minor pentatonic, major, minor, Dorian, Mixolydian, blues or whole tone. The pads and the strip only play notes that belong, so anything you play sounds musical. Switch on chord mode and each pad plays a full triad.

SHAPE THE SOUND
Six sounds to start from: Dreamy, Punchy, Wobbly, Glassy, Warm bass and Retro. Drag the XY pad from dark to bright and from dry to wet, let it spring home, or draw a motion and it loops in time with the beat.

LOOP WHAT YOU MAKE
Set the tempo, add a drum groove, turn on the arpeggiator, and loop what you play. Record your takes and share them.

MAKE IT YOURS
Choose a color theme and an alternate app icon. Left-handed? Flip the layout so the pads sit on the left.

ALSO PLAYS ON iPHONE AND iPAD
No fold? Hinge Harp lays the strum strip, XY pad and pads out on any iPhone or iPad, in portrait or landscape.

No account, no ads, no subscription. Pay once and it's yours.
