## Description

Scales are central to music. Intervals are central to scales. Tuning intervals is a complex process that must constantly be refined by the musician.

Scale Master was designed by professional musicians and educators and developed by experienced software consultants and is a tool providing transparency to intonation deficiencies so that tuning is faster and more accurate.

Through the use of "droning" sounds across various intervals, Scale Master provides a means of practicing intonation.

Who can use Scale-Master?

- Musicians (Professional and Amateur) striving to further perfect their tuning ability
- Student Musicians just starting to come to grips with the challenges of Just Intonation within the ensemble
- Band, Orchestra and Choral Directors looking for a way to help their ensembles "HEAR" what "In Tune" is
- Music Theory, Music Appreciation and General Music teachers wanting to demonstrate scales, intervals, patterns and intonation

How it works:

Using Equal Tempered tuning, select a root pitch and octave, then select the scale interval above the root pitch and select "Play". The generated droning sound will be a real-time interval based on Just Intonation producing the greatest resonance.

There are a total of 780 droning renderings available for the first release.

Beyond simple drones, you can also select a scale mode to display. The corresponding intervals will be high-lighted allowing easy, visual recognition of scale patterns. Scales included are:

- Chromatic
- Major
- Natural Minor
- Harmonic Minor
- Blues
- Whole Tone
- Major Pentatonic
- Minor Pentatonic

There is also a scale "Auto-Play" function that will play the droning root and the corresponding scale interval in half notes at quarter=60bpm allowing the musician to work with tuning and harmonizing in real-time.

There are a total of 420 scale configurations available for the first release.

What Others are Saying:

"I think your app will be widely useful, better and more convenient than the typical tuner.  It also will be a good companion tool for users of my 'Breakfast' Intonation practice booklet." 
     David Schwartz

"This new app looks wonderful to me, Gil!!  A great teaching tool not only for trombonists but also for music theory and many more applications for musicians.  Great idea!!"
     Tom Senff - Trombone Professor and Trombonist with Stan Kenton Orchestra

"WOW! I like this a great deal. I teach AP Music theory. I think this would be tremendously helpful with drilling intervals."
     Rob Optiz - High School Band Director

"When my students use this, they seem to adjust automatically in the correct direction."
     Private Trombone Instructor

## Review summary

Users widely praise Scale-Master for its drone-driven ear training, easy, on-screen interface, and usefulness as a portable pitch pipe for both students and professionals. The main drawbacks mentioned are a lack of multi-octave scales (only one octave is currently supported, with frequent requests for two or more octaves) and occasional visual timing issues between the scale display and notes. Overall, it’s a powerful, free practice tool that many rely on, with a clear demand for feature improvements.

### Pros

- Effective drone-based tool for ear training and improving intonation.
- Easy to use with a simple, one-screen interface.
- Versatile for practice as a pitch pipe and useful for teachers and performers.
- Free to use and provides robust drone functionality.

### Cons

- Lacks multi-octave scales; current support is limited to one octave, with repeated requests for two-octave/multi-octave scales.
- Occasional visual timing issues between the scale display and notes.
