Backing track with no delay
The student sings to the backing track, and you hear the voice and the music together — right on the beat.
Features
Two modules
For singing lessons: a clean voice, a backing track with no delay, warm-ups and voice analysis.
- Clean voice soundWith headphones — no echo cancellation or noise suppression cutting high notes. “Student’s sound”: their microphone volume, headphones or speakers — without asking the student.
- Synced backing trackThe student sings to the backing track without internet delay. Tempo, key ±5, loop a section, markers on the waveform.
- Singing along to YouTubeThe video on half the screen for both of you: “Student mode” — the student sings along to the video, “Teacher mode” — the teacher controls the video.
- Warm-upsOver 20 ready-made warm-ups with accompaniment, plus your own exercise: scale, articulation, style, ensemble. Straight to the player or as an MP3 for homework.
- Voice analysisReal-time pitch, vibrato, intervals — and the student’s progress from lesson to lesson.
- Piano at handA compact panel at the bottom, 49 to 88 keys when needed; volume right above the keys.
For piano lessons: a big keyboard across the bottom of the screen, sheet music in the center, video on the sides.
- Big keyboard49, 61, 76 or 88 keys. Play with the mouse, the computer keyboard or a MIDI keyboard.
- Your notes and the student’sPressed keys show in different colors; the staff shows the notes, intervals and chords being played.
- Sheet music in the centerA PDF or screen share in the middle, both videos on the sides. Pencils and colors, zoom, “Undo” — ⌘Z.
- MetronomePlays on the student’s side or yours — whoever plays to the click hears it with no delay.
- Clean instrument sound“Headphones” — sound with no processing at all, “Speakers” — with echo cancellation, no echo.
- Together with the studentThe student switches to the mode together with you, and the button panel tucks away to the side so it doesn’t take up space.
Teacher’s and student’s notes
Who plays what is marked differently on the keyboard, for both of you at once.
Intonation on a graph
You can see where the student hit the note and where they “drift” — note by note, in real time.
Real screens
This is what a lesson looks like
Not mock-ups — frames from the lesson room and the teacher’s dashboard, exactly as you’ll see them on day one.
Everything in one window
Both videos, backing track, piano, sheet music, warm-ups and voice analysis — no separate apps or tabs. The student sees the same thing.
Backing track in sync with the student
The track plays on the student’s side, so the voice lands right on the music. Verse markers, section loop, tempo and key ±5 — set to the student’s voice.
Voice analysis
Real-time pitch, intonation accuracy, vibrato and intervals. You can see where the student is on the note and where they “drift”.
Warm-ups with accompaniment
Ready-made exercises and your own in a minute: range, tempo, accompaniment. The exercise moves up a semitone by itself, and you can save the recording for the student’s homework.
Both of you see the sheet music
Open a PDF from storage and draw right on the page. The student sees every mark and every page you turn.
“Piano” mode
One click and the room is ready for a piano lesson: a keyboard across the bottom of the screen, MIDI, a staff and a metronome.
Your dashboard
Lessons, hours, students and how regularly they study, files and homework playlists. The room link is permanent — one for all lessons.
Video lesson for singing
Sound without “phone-call” processing: with headphones the voice comes through clean, with no echo cancellation cutting high notes. “Gallery” or “Speaker”, a floating window, a connection indicator for each side.
Synced backing track
Upload a backing track — you choose where it plays, so the singer hears it without internet delay. Tempo, key ±5, loop a section and markers on the waveform.
88-key piano
Play with the mouse, the computer keyboard or a MIDI keyboard. Your notes and the student’s look different, the staff shows what’s playing, the metronome plays on the student’s side or yours.
Warm-ups
Over 20 ready-made warm-ups with accompaniment and your own exercise in a minute: scale, articulation, style, ensemble. Save it as a file — and the homework is ready.
Sheet music and lyrics
Both of you see a PDF or a photo of the sheet music. Draw with a pencil and highlighter right on the page, turn pages — the student sees everything instantly.
“Piano” mode
A big keyboard across the bottom of the screen, sheet music or a screen share in the center, video on the sides. The student switches to the mode together with you.
Lesson recording
The “Record” button saves the lesson to a video file — with both videos and sound, so the student can rewatch it at home.
Teacher’s dashboard
Lesson stats, file storage for backing tracks and sheet music, playlists for students — to listen and view sheet music at home via a link.
