HIM Scale Builder
Choose an exercise, set the range, direction, and speed, then hear and download a clean piano-reference track built around your voice.
Your voice is not fixed. Your practice track shouldn't be either.

Select the exercise, range, direction, speed, and metronome.
Scale Builder creates the piano-reference exercise across the range you chose.
Play it immediately or download the full track to your phone.
The Product
Most vocal warm-ups are fixed. Scale Builder lets you choose the exercise, the working range, the direction, and the speed before you practice.
Hear It for Yourself
The Practical Difference
Fixed practice tracks expect you to adapt to someone else's range, tempo, direction, and stopping point. Scale Builder lets the track adapt to you.
Use a smaller range on recovery days. Change the speed without changing pitch. Continue the same exercise higher or lower as the voice develops. Save the exact version you want to practice.
There is no magical scale. The method lives in how the human performs the exercise.
Why Scale Builder Exists
I built Scale Builder for my own practice and for the singers I work with. Generic tracks kept ending at the wrong place, moving too quickly, or forcing the singer into somebody else's range.
I needed a tool that could change with the voice in front of me, so I built one. I eventually decided to make it available to everyone.
Built for myself. Refined for my students. Made available to every singer who needs more control over their practice.Explore Human Instrument Method

Practice Conservatively
Pain is not progress. Begin conservatively and stop immediately if singing or practice causes pain, discomfort, persistent hoarseness, breathing or swallowing difficulty, or anything that feels wrong.
Human Instrument Method provides vocal education and training, not medical diagnosis or treatment.
