I just started working my way through a book called Composing Music: a New Approach and i was thinking it would be a really fun thing to do with a community

You can easily get a pdf off google

The book consist of 16 chapters covering a different aspect of music composition. Each chapter is a series of composition exercises each with its own rules and limitations that help you explore and experiment with different aspects of writing music

The book does assume a basic level of music theory understanding but honestly not that much

Anyone interested in doing this as a community? We'd probably do a chapter a week then have a specific day for sharing and giving each other feedback on that weeks compositions.
