Multimodal Expert Instruction Samples - Musical Instrument Lessons with Channel-separated Audio and Video
A music teacher and a student work through two one-on-one lessons: both voices and both instruments on separate tracks, the student on camera, with the lesson plans, the instructions given to each side and both sides' post-lesson ratings alongside.

Sister collection: Peer Collaboration, two non-experts building circuits under asymmetric information. Compare expert-led instruction with peer collaboration.
In this sample: 6 interactions · 53 minutes · 2 lessons · 1 studio session
Audio: 48 kHz / 32-bit speaker-separated voice tracks and instrument direct inputs · sub −60 dB recording noise floor · RT60 < 90 ms
Video: 1080 × 1920 / 30 fps portrait camera original · continuous view of the student
6K source video: available in the full collection · not included in these samples
What makes this collection different?
- Real expert instruction, not scripted dialogue. A working music teacher teaches a real student; nothing is staged line by line.
- Structured lessons with a check before and after. Lesson plans follow Bloom's mastery-learning framework and Rosenshine's Principles of Instruction: baseline assessment, explanation and demonstration, guided practice with corrective feedback, assessment of improvement.
- Speech, playing and video share one timeline. Separate voices, each instrument's direct input, the camera on the student and the transcripts can be analyzed together.
- Objective-based. Teacher and student each rate objective attainment and how much was learned; the lesson plans and the instructions given to each side are included.
View samples
Choose any part of a lesson to inspect it on one synchronized timeline:
- The student on camera: a continuous portrait view of the student, hands and instrument.
- Four separate tracks: instructor and student voices and each instrument's direct input as waveforms with independent on/off controls.
- Timed transcript: speaker-labeled, machine-generated turns aligned to playback.
- Lesson context: the lesson plan and the instructions given separately to the teacher and the student.
- Outcomes and metadata: both sides' post-lesson ratings, lesson, part, duration, participant information and recording specifications.
Transcripts were generated with nvidia/parakeet-tdt-0.6b-v3 and are not human-reviewed.
The six interactions
| Lesson | Duration | Session |
|---|---|---|
| Diminished chords and their function · pre-lesson check | 1:22 | S020 |
| Diminished chords and their function · lesson | 17:36 | S020 |
| Diminished chords and their function · post-lesson check | 3:24 | S020 |
| Learning "I Want to Tell You" by the Beatles · pre-lesson check | 1:17 | S020 |
| Learning "I Want to Tell You" by the Beatles · lesson | 24:35 | S020 |
| Learning "I Want to Tell You" by the Beatles · post-lesson check | 4:19 | S020 |
One teacher and one student across two lessons; each lesson has a check before, the lesson itself and a check after.

Terms
Fluid Concepts provides these recordings solely for evaluation by people who have agreed to these terms on the data page.
- Evaluation only. Use the samples to evaluate the Multimodal Expert Instruction - Musical Instrument Lessons with Channel-separated Audio and Video collection for a possible engagement with Fluid Concepts. Do not use them to train, fine-tune or evaluate a model for any other purpose without written agreement.
- No redistribution. Do not share the files, or derivatives of them, with anyone who has not agreed to these terms on the data page, and do not post them publicly.
- People. The voices and faces belong to paid participants recorded with their consent; the video shows the student. Do not attempt to identify anyone. Participants are identified by studio codes; first names spoken in the sessions are left as recorded.
- No cloning. Do not use the recordings to clone, synthesize or imitate anyone's voice, or to build a digital likeness or avatar of any participant.
- Revocation. Access can be withdrawn at any time. On request, delete all copies.
- No warranty. The samples are provided as they are.
