Hey everyone! 👋 I'm a jazz piano student who got tired of flipping through voicing books. So I built BeingJAZZER — a desktop app that displays chord voicings on a grand staff and drills them with a metronome. The idea is simple: pick a chord type, hit play, and practice voicings as they cycle through random keys. You can also plug in a MIDI keyboard to see what you're playing in real time. I built this with Tauri (Rust) + VexFlow, so the app is only 3.6MB. Would love your feedback — especially from fellow jazz musicians! 🎹
