The Arithmophone is a new kind of musical keyboard, a rethinking of the way we can interact with electronic music instruments. It provides easy access to many familiar and unfamiliar notes in colourful two-dimensional layouts and is a tool for exploring different kinds of tuning schemes, both just and tempered.
Introducing the second generation of the Arithmophone family of musical instruments:
The Arithmophone Korale is an easy-to-play instrument that is well suited for beginners and for smaller screens/mobile devices. It offers a wide selection of diatonic and pentatonic scales in just intonation, and direct access to many sound-shaping parameters.
The Arithmophone ToneHive takes everything to the next level by providing a 41-note just intonation keyboard that unleashes the power of the 7th harmonic. It is best suited for those who want to take a deep dive in to the wonderful world of just intonation.
Each of these instruments is available as a Standalone Web App with a built-in synthesizer, that allows you to play it on any phone, tablet or other touch screen computer. Each is also available as a MIDI interface that lets you control compatible hardware or software synthesizers.
