The Metronome plugin adds an interactive metronome feature to Obsidian notes, perfect for musicians. It allows users to set the tempo (BPM), meter, and instrument sounds, while providing visual styles such as pulse, pendulum, and dots. The plugin can be customized with options like tick and tock notes, size, and auto-start behavior. It also includes features like a countdown timer and automatic stop after a specified duration. Integrated with music notation plugins, it offers a seamless way to practice music, whether for live performances or personal rehearsals. Users can also tailor it to fit their Obsidian theme.
