Finding a partner to practice daily with is hard
Kotekan needs two players interlocking. Coordinating schedules with a teacher or partner means most days, you don’t practice at all.
Learn to play gamelan on your phone
Learn various kotekan patterns at your own pace, from your phone, until they feel natural to play.
No instructor or partner to play with? No problem
Gamelan was never meant to be played alone, but finding an instructor or a partner to play with is not easy, and that makes practicing feel almost impossible.
Learning resources are hard to find
Notes and patterns are passed down from mouth to mouth. Finding them is tiring and time-consuming, so you waste the time you’d rather spend playing.
No one to correct you
Don’t let unnoticed mistakes become a habit. Kotek guides you to play with the correct timing and accent.
Kotek helps re-create the learning environment
Keep waiting on a partner and a resource, and you will never practice.

Everything you need to know
We’ve answered the questions people ask most often about Kotek.
What do I need before I start?
You’ll need a physical instrument to practice on. Kotek is built for playing on a real instrument, because that’s how it can help you build muscle memory and get the feel of it in your hands. You’ll also need a tripod or stand to hold your phone above the instrument, camera pointing down, so both of your hands are free to play.
What instrument can I play with this app?
Kotek is built around the gangsa of the gong kebyar family, an instrument with bronze keys over bamboo resonators, played with a single mallet while the left hand damps. It ships with a calibrated profile for that instrument, and because every village tunes differently, the app is designed to be calibrated per instrument rather than assuming a standard tuning.
Is this app beginner friendly?
Yes. Practice mode is the default for first-time players. There’s no score and no fail state: Kotek waits for you to hit the right key before moving on, and you can slow the tempo down until the pattern sits in your hands. Scoring only comes in when you decide you want it.
