The problem with just intonation – a visual guide

Tuning is the final frontier of my musical understanding. I start reading about it, and then I hit a big table of fractions or logarithms and my eyes immediately glaze over. However, tuning is important and interesting! So I continue to struggle on. Fortunately, as with so many music theory concepts, the right computer software can open up lots of new learning avenues. I have been having a great time with MTS-ESP by Oddsound. It was designed to help you hear and play different tuning systems, but it also visualizes them in an attractive circular way. If you read this blog, you know how much I love a good circular music visualization scheme.

So here is the basic problem with tuning. An ideal system (for Western people) would be based on the natural harmonic series, because we love how harmonics sound. This kind of tuning system is called just intonation. It sounds lovely! Unfortunately, just intonation makes it impossible to change keys or tune your guitar. Let’s use MTS-ESP to figure out why that is. Continue reading

The Groove Pizzeria

For his NYU music technology masters thesis, Tyler Bisson created a web app called Groove Pizzeria, a polyrhythmic/polymetric extension of the Groove Pizza. Click the image to try it for yourself.

Note that the Groove Pizzeria is still a prototype, and it doesn’t yet have the full feature set that the Groove Pizza does. As of this writing, there are no presets, saving, or exporting of audio or MIDI. However, you can send MIDI via the IAC bus to the DAW of your choice (Mac OS Chrome only). You can also record the Groove Pizzeria’s output using Audio Hijack.

Like the Groove Pizza, the Groove Pizzeria is based on the idea of the rhythm necklace, a circular representation of musical rhythm. The Groove Pizza is a set of three concentric rhythm necklaces, each of which controls one drum sound, e.g. kick, snare and hi-hat. The Groove Pizzeria gives you two sets of concentric rhythm necklaces, each of which can have its own time duration and subdivisions. This means that you can use the Groove Pizzeria to make polyrhythm and polymeter.

QWERTYBeats design documentation

QWERTYBeats logoQWERTYBeats is a proposed accessible, beginner-friendly rhythm performance tool with a basic built-in sampler. By simply holding down different combinations of keys on a standard computer keyboard, users can play complex syncopations and polyrhythms. If the app is synced to the tempo of a DAW or other music playback system, the user can easily perform good-sounding rhythms over any song. 

This project is part of Design For The Real World, an NYU ITP course. We are collaborating with the BEAT Rockers, the Lavelle School for the Blind, and the NYU Music Experience Design Lab. Read some background research hereContinue reading
