"The Arithmophone Pentatone is a new iOS music app featuring an easy-to-play pentatonic keyboard and a built-in synthesizer."

"Pentatone is available now in the Apple App Store, for iPhones and iPads running iOS 15 or above.

The app is completely free (no in app purchases, no ads or tracking).

Most iOS music apps either give you piano keys or a grid-based interface. Pentatone takes a fresh approach, optimised for the ergonomics of touchscreen devices and inspired by instruments like the kora and mbira. It also has a sophisticated scale selection system that includes all the common pentatonic scale types and unlocks some more unusual ones.

Pentatone features:

An easy-to-play keyboard, split for two handed playing

An original pentatonic scale system with 9 selectable scales, in just intonation or standard tuning

A custom Audiokit-based synth engine (binaural 2x2 operator FM with stereo detune, resonant filter, delay and reverb)

25 preset sounds with macro sliders for tone and ambience

Initial touch and aftertouch response, both polyphonic

User feedback from the public beta:

"this has such a nice design and ui, colors are fresh and remind me of piet mondrian"

"Sounds incredible and can’t wait to use this in my workflow!"

"This is an inspiringly expressive instrument, my friend! Really a joy to interact with."

"Amazing! Love the simple UI and the musical keyboard. Also the sounds are lovely!"

"It’s very fun to play!"

"Looks beautiful!!!"

The app is completely free (no in app purchases, no ads or tracking)."

Introducing the Arithmophone

"The Arithmophone is a new tool for exploring musical intervals from your computer, tablet or phone. It is a musical keyboard for touchscreen devices, you can play it directly from your browser using the built-in sounds or connect it to other instruments via MIDI.

"The Arithmophone is a new kind of musical keyboard, a rethinking of the way we 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.

It currently exists in two forms:

The Arithmophone web app is a self-contained instrument that you can play from your computer, tablet or phone. It works best on touchscreen devices in landscape orientation (try an iPad or something of similar size if possible: the bigger the screen, the easier it is to play the keyboards).

The Arithmophone MIDI is a keyboard interface for controlling synthesizers. If you work with a DAW and software instruments, or if you have a hardware synthesizer you’d like to control through your (touchscreen) computer, this might be interesting for you.

Future ambitions for the Arithmophone project include a native iPad app with MIDI output as well as a hardware prototype.

I’ve made a manual that provides more details about the Arithmophone. I’ve also made an interactive guide to the building blocks of melody and harmony that explains some of the basic principles behind the Arithmophone in an accessible way."
