Music Analysis

Try it now!

This is a tool for composing or analyzing music.

It's currently a proof-of-concept, and, as such, it is very unoptimized performance-wise.

Some editing tools are currently keyboard-only.
The keys 1 to 7 input scale-aware pitches.
Use the arrow keys to move notes and the cursor around.
Move the cursor while holding down Shift to select an interval of notes.
Move a note while holding down Ctrl to change its duration.
Press Enter to unselect all notes.
Use the Alt key for faster steps while moving stuff around.
You can also click on elements with the mouse to select them.
Also, range-select elements by dragging the mouse.

In the future, it should support:

• Full roman numeral harmony analysis
• Save/Load from Dropbox, URL, or local files
• Import/Export from MIDI, tracker, and other formats
• Song parameter changes, such as tempo
• Note pitch bending
• Multiple tracks and instruments
• Note/Track parameter changes, such as note velocity

Uses piano samples from http://theremin.music.uiowa.edu/MISpiano.html.

In order for audio samples to load properly when developing locally, set up a local HTTP server, such as python3 -m http.server 80.
