What is the circle of fifths? 

It is a circular diagram showing the twelve absolute notes of our western musical notation system represented like numbers on a clock face: c / b# is in the 12 o'clock position, g corresponds to 1 o'clock, etc. Moving clockwise around the circle, the interval between adjacent tones is always a fifth.

What do the names of the scales mean?
The pre-installed scales all bear names originating both from western and eastern cultures.

For example: "Ionian / Major, Bilawal (A2)":

Ionian / Major = the western term for the Major scale
Bilawal = the Indian term for the Major scale
A2 = the position of the scale in N. A. Jairazbhoy’s "System of the 32 thaats".

What is the purpose of the Sa-Ring?
The Sa-Ring indicates the relative note names Sa-Re-Ga-Ma-Pa-Da-Ni, common in the Indian music system. With the help of the Sa-ring, the position of a note in a scale can be easily recognized:

Sa - Tonic Note
Re - Minor Second
Re - Major Second
Ga - Minor Third
Ga - Major Third
Ma - Perfect Fourth
Ma - Augmented Fourth (written with a line across the top)
Pa - Perfect Fifth
Da - Minor Sixth
Da - Major Sixth
Ni - Minor Seventh
Ni - Major Seventh

If the notes Re, Ga, Da, Ni are lowered a semitone step, they become Re, Ga, Da, Ni, (underlined).

If the note Ma is raised a semitone step it becomes Ma (written with a line across the top).

The Tonic Sa and the Fifth Pa are not allowed to change in the Indian music theory.

How can I change the tonic of a scale?
The tonic can be changed by:

• Turning the polygon with the aid of the dark grey spot. 

See manual: section 3. Transpose a scale

• Turning the Sa-ring with the arrow - buttons.

See manual: section 6. Change the keynote within a scale

Why is the tonic of a preset scale initially set to "c"?
There are technical reasons for this. Even if, for example, a scale with the tonic note of "g" is saved, upon retrieval from the database, the system will restore its tonic to "c". However, by turning the polygon, the scale can be transposed quickly and easily back into whichever key you intended.

See manual: Section 3. Transpose a scale

Why does EasyScale sometimes interchange the tonic and the octave of the tonic?
The notes of a scale must be entered commencing from the tonic and progressing upwards to the next higher octave! If the notes are inputted downwards (from the higher to the lower octave), EasyScale will try to reorganise it to the correct upward progression, resulting in octave notes being reversed.

See manual: Section 7. Compose new scales and intervals

Why does EasyScale sometimes not recognize a scale, even though all the notes are correct?
In order to allow EasyScale to indicate already stored scales or intervals, the notes of a scale must be entered commencing from the tonic and progressing upwards to the next higher octave: Start with the tonic or root-note by turning the dark grey spot, then add higher note(s). In the case of scales, finish by tapping the tonic.

See manual: Section 7. Compose new scales and intervals

Can I save factory-scales under a different name?
If a scale already exists in the factory-scale-list, you cannot save it under a different name.

Why does EasyScale sometimes not accept the entering of a note?
The range of notes in EasyScale includes 3 octaves. Try entering the note at the next higher or lower octave: First turn the dark grey spot one rotation clockwise (or counter clockwise), then enter the desired note(s).

How many own scales can I save in EasyScale?
EasyScale has the ability to store practically infinitely numbers of scales and tone-sequences.

System requirements: iPhone - iPod touch - iPad with OS 3.1.3 or higher.



Have fun with EasyScale!
