Boutique upright + real metal hammers
for one-of-a-kind piano sound.

About the Library
The moment we heard Mattias Krantz’s new experiment — replacing every single hammer on an upright piano with real, metal hammers — we knew we’d found something truly unique that could inspire musicians around the world. It’s not quite like anything you’ve ever heard before. The sound is reminiscent of a particularly powerful and full-voiced harpsichord, with the dynamic responsiveness of a regular piano and the percussive nature of a hammered dulcimer.
While it’s a fun conceptual experiment, we think you’ll find that Hammer Klavier is also beautiful and a delight to play! Mattias worked with us to record his instrument in great depth; it has been carefully sampled to the fullest so that it’s every bit as playable and realistic as a standard piano. We created it with the same love and care that makes our Pearl Concert Grand a staple choice for many composers.
Think of this not as a sound design toolbox but as a custom upright piano with a unique voice. While Mattias might have destroyed a piano to get this great sound, we think you’ll agree it was worth it.
The Engineer Series
Mattias Krantz is a guitarist and YouTuber known for his wild, imaginative experiments with pianos and guitars. We are collaborating with him to bring his unique instruments to composers and musicians around the world. Hammer Klavier is the first instrument in this series, but it won’t be the last!
