Exercise
Select the pattern you want to train, such as Pentachord, AH-gility, or Do Re Mis for Days.
How to Use
Build the practice track your voice needs today.
HIM Scale Builder creates piano-reference vocal exercises from the settings you choose. Pick the exercise, note range, direction, speed, and metronome, preview it, and use Founding Edition to download that exact track.
Free Demo and Founding Edition
The Free Demo lets you preview playback in the C3-C4 selected note range. Founding Edition unlocks the full C1-C6 selectable note range and downloadable MP3 tracks.

Choose the exercise
Mode
Major and Minor choose the variant of exercises that support both. Some custom exercises use fixed intervals.
Direction
The Direction control changes the internal exercise pattern, such as whether a pentachord moves upward or downward inside each phrase.
Starting Note and Ending Note
These set the selected phrase anchors. An exercise can still sound notes above or below those endpoint labels.
Shape the track
Play Ascending moves the generated track upward by half step through the selected note range. Play Descending moves the generated track downward through the corresponding descending track.
Descending Offset shifts the descending track when the selected range allows it. If the offset would push phrase anchors outside the allowed range, the app limits it and shows a notice.
Speed changes tempo, not pitch. The Metronome toggle adds click support to both playback and the saved track. The piano roll highlights the current pitch class during playback so you can see what is sounding.
Playback and downloads
During playback, configuration controls are hidden so the captured audio matches the settings that started the session. Pause and Resume are for practice flow; Stop fully stops the session.
Natural completion creates a complete MP3 when capture is available. Pressing Stop creates a partial MP3 when enough audio has been captured. Changing the configuration invalidates an older prepared download for the previous settings.
The zero-pain rule
Pain is not progress. Stop immediately if anything hurts. HIM Scale Builder is an educational practice tool, not medical diagnosis, medical treatment, or a substitute for appropriate care. Read the Educational and Safety Disclaimer before training.
