See the work, not just the clock
Review what was played, when it was played, and how the performance changed across a session.
Built for serious piano practice
Turn practice time into visible progress.
Practice Meter reads the MIDI signal from your child's keyboard and makes each session measurable— what they practiced, how consistently they played, and where technique began to break down.

Pattern detected
The turn is less even than the rest of the scale. Slow the top four notes and repeat.
Representative product view. Metrics depend on the exercise and captured MIDI data.
Piano lessons happen once a week. Progress is built on the other six days.
Practice Meter gives families and teachers a shared, objective record of the work between lessons.
The practice gap
“Did you practice?” is the wrong question.
Minutes alone cannot tell you whether a student repeated with attention, rushed through a difficult turn, or reinforced the same uneven motion.
Find the exact weak point
Break a run into note-level timing, accuracy, articulation, and dynamic signals instead of relying on a vague impression.
Make repetition intentional
Use specific feedback to decide what to isolate, slow down, and repeat next.
Bring better data to the lesson
Give teacher and student a concrete record so lesson time can focus on diagnosis and musical decisions.
From key press to useful feedback
A clear measurement loop, designed around the instrument.
MIDI captures the exact note, onset, release, and velocity. Practice Meter turns that signal into a structured practice record.
01
Connect
Plug a MIDI keyboard into a desktop or laptop and allow browser access.
02
Play
Practice naturally while note events are captured in real time.
03
Analyze
The system separates hands, identifies the exercise, aligns notes, and computes technique signals.
04
Act
Review the session and choose a specific passage or behavior for the next repetition.
For ambitious families
High standards work better with precise feedback.
Support disciplined practice without hovering over the bench. The goal is not surveillance—it is helping a student learn to hear, measure, and correct their own playing.
A session record grounded in keyboard data
Separate views for accuracy, timing, articulation, and dynamics
Progress history for students and connected teachers
Concrete next steps instead of generic encouragement
Before you begin
A two-minute setup.
You need a MIDI-capable digital piano or keyboard, a USB cable, and a compatible desktop browser. Acoustic-piano audio is not currently supported because the analysis depends on precise MIDI events.
- Digital piano or MIDI keyboard
- USB MIDI connection
- Desktop or laptop computer
- Chrome or another browser with Web MIDI support
