Lifetime musician’s companion!

This is a universal app, you can now install on all your iOS devices (iOS 6.0 or later), however the app is not recommended for iPod touch.
* Minimum hardware requirements: iPhone 4S, iPad 3rd generation, iPad mini or later.

New and improved in every dimension!
So, what’s new in this edition?

• New Features
- The Guide: You will discover regular patterns or algorithms.
Use the guide dots to understand the circle better and apply your own interpretations (e.g. simple math calculations). Simply rotate those small colored dots (not rotate the circle!!) to see how they relate with other keys. This guide proves that all music can be transposed to any keys and you will see that the musical notes (intervals) remain equally spaced. The more you try this guide, the more you will be amazed at what these little dots do. (Hint: Double tap - return to original position)

- Intervals Tables:
All possible intervals are organized (over 290 intervals) in one page. Simply scroll up and down to see other intervals on the page. You can listen to the harmonic and melodic sound of the intervals with the musical notation and letters.

- Change background:
You can now change background. Try a different background whenever you want, it is fun! Feel fresh when you study (8 backgrounds x 8 different colored circles = 64 combinations!).

- Enharmonic keys: Enharmonic notes are important in music as is key signature.

• Improvements
- New design and User Interface (UI)
- About 25% louder in sound
- Performance: built with the latest tools and technology available
- User interactions
- Scales: added both accidentals and key signatures
- Triads: 1st, 3rd and 5th notes can be selectable which is useful in the inversions

• Changes
- Supports only portrait mode for optimal performance and stability

The ultimate goal of this app is to master the comprehensive musical materials with ease. For example, the interval itself is a pretty wide area, which takes perhaps a lifetime to learn. This app breaks down intervals into as small units as possible in order to that you can achieve them in a step-by-step manner.

• Main benefits
- Mastering Circle of 5ths and key signatures
- Mastering all triads and scales
- Improving aural perception
- Better in chord progressions
- Better in transcription and arrangement of music
- Musical confidence and improvement in teaching music
- Much more
