OnlinePianist is built for learning piano songs with animated hand guides and a subscription song library. BeatKey Virtual Piano serves a different need: producers and musicians who want to play notes, see their exact Hz frequencies, check chords, and integrate with a full production suite. No subscription. No song library. Just a clean, functional piano with real-time frequency data.
"Learn to play this song" - animated hand guides for specific songs, requires subscription for full library access.
"What note is this, and what Hz is it?" - a production reference tool that shows frequency data and connects to BPM, chord, and delay tools.
Free virtual piano. No subscription. No account. Hz display included.
Open Virtual PianoOnlinePianist is a piano learning platform that provides animated hand guides for popular songs. Users can follow along with falling notes or hand position visualizations while a song plays. It has a catalog of thousands of songs and a mobile app. The free tier is limited; the full song library requires a subscription at $9.99-$19.99 per month.
OnlinePianist does not show Hz frequencies or MIDI numbers. It does not detect BPM or key from uploaded audio. It is designed for learning songs, not for music production workflows.
