The app can\nonly be accessed via mobile.\n\n## Background\n\nI designed and developed Polymetro in March of 2020, when I was learning Magnus\nLindberg's Twine. The piece is filled with polyrhythms, many of which I have\nnever encountered before.\n\n\u003cdiv align=\"center\"\u003e\n\u003cimg src=\"https://raw.githubusercontent.com/somecho/polymetro/master/assets/twine.png\" width=\"720\"\u003e\n\u003cp\u003e\u003cem\u003esnippet of Twine\u003c/em\u003e\u003c/p\u003e\n\u003c/div\u003e\n\nIn order to learn these rhythms, it was necessary to *flatten* the polyrhythm\ninto one composite rhythm and subsequently learn it as a chunk. This wasn't\nalways easy when faced with a dense rhythm, like 9 against 8. To easy this\nprocess for myself, I set out to create Polymetro.\n\n## Development\n\nThe idea was to have a digital metronome that could play both single rhythms and\npolyrhythms. Setting the desired metrum, the pulse grid would adjust itself to\nvisually show the number of beats per cycle.\n\n\u003cdiv align=\"center\"\u003e\n\u003cimg src=\"https://raw.githubusercontent.com/somecho/polymetro/master/assets/pulsegrid.png\" width=\"720\"\u003e\n\u003cp\u003e\u003cem\u003escreenshot of pulsegrid\u003c/em\u003e\u003c/p\u003e\n\u003c/div\u003e\n\nEach glyph in the pulse grid could be toggled by tapping on it, cycling between\nthree states: strong, weak and silent. \n\nThe metronome is also trilingual. Clicking on the settings, a modal will appear\nwith the option to select between English, German and Chinese.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsomecho%2Fpolymetro","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsomecho%2Fpolymetro","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsomecho%2Fpolymetro/lists"}
