Composing Music in the Cloud
summary
An HTML5 single‑page app on cloud foundry calls two Spring Boot microservices — a counterpoint composer and a chord analyzer — hosted on Pivotal Web Services, with source on GitHub under Apache‑2. The composer posts MIDI pitch arrays (0–127) and mode/species parameters and returns MusicXML which populates an embedded NoteFlight score; the analyzer returns chord labels (e.g., G major) via JSON using a jfugue‑based library. Demo composes first/second/third species counterpoint from a cantus firmus (Twinkle Twinkle), accepts WebMIDI input, and deploys with mvn and cf push.
