harmonypartition works simply and cleanly with MIDI files. Using the music21 package, harmonypartition is able to analyze a MIDI file in exactly the same way it analyzes an audio file. Results from MIDI are cleaner than those from audio – though not necessarily better, since resonance and continuity play such a key role in analysis, […]

harmony=>audio
I’ve built the harmonypartition system to generate harmonic sequences with just a few small numbers. Here is a simple one, built from simple piles of sine waves. Later they can of course expand to MIDI and DAW systems. harmony as a sequence So to begin: the following sequence: …can generate this chord sequence: This is […]
audio => harmony
harmonypartition can harmonically analyze audio files by dynamically seeking and organizing tonal continuities. In a great many musical cases, these continuities take the form of familiar keys and chords. example: vi-ii-V-I Here, for example, is a vi-ii-V-I progression in C major, generated from fourier analysis of a .wav file: Here is the same progression, analyzed […]
a new direction
The power of electronic music – even the most dedicated analogue instrumentalist must admit – is beyond question. Though they do not cover the same musical ground as a finger on a string or breath in a column of air, the filters, echoes, synthesizers, and effects applied to waveforms in electronic music have enormous effect. […]
Feet on the Ground
As you start to play, aim for solidity in left and right hand. Your left hand should feel full, fat contact with the string; the hairs of the bow should sit thickly and exactly on the string.. Compare the solidity of contact in your hands with the solidity of your feet on the ground. Try […]
Practising with a Mirror
Practising with a mirror is extremely useful – for both hands. However, one must not become too self-obsessed. When practising with a mirror, try to position yourself so you do not see your own face. You will gain much in the way of objectivity
Your Fingers are Sightless Animals
The fingers of your left hand cannot see. You must give them eyes with your ears. Play any passage, concentrating on how your fingers depend on your ears for guidance.
The mysterious energy of Pac Man
As you play, your left and right hand are brought together not only by the bow and the string. Your arms, the bow, and the string make a complete circuit with a Pac-Man shape. Energy can flow freely in this circuit.
Tuning the violin like a drum
Every time you use your left hand to choose a pitch, you must be confident in its tuning. It is as though you are playing the timpani: once you tune it, you can concentrate much more clearly on how it is struck, and how it makes sound. And know, when you start playing, that what’s […]
Drawing the string as a bow
Play a slow scale, watching the small part of the string between the bridge and the bow hair. Each time you draw the bow, you will see the string push to the left (for up bow) or the right (for down bow). Do your best to maintain this angle in the string as you play, […]
