Description
Circle Theory is a Circle Of Fifths (sometimes known as a Circle Of Fourths). The Circle Of Fifths is a tool for musicians to assist them in seeing the relationship between notes, provide key signatures for both major and minor scales, assists in transposing between keys, and it also has a helpful guide to figure out note intervals per musical mode. An iPad VGA adapter can be used to view the circle on an external screen or projector.
Shortcuts:
• Tap or drag on the outer ring to change the tonic note / key signature
• Double-tap the outer ring to cycle through the inner ring displays
• Double-tap the center of the circle to cycle through the clefs
• When the inner ring is displaying a musical mode, drag the inner ring to select a new mode
• When the inner ring is displaying the transposition assistant, drag the inner ring to select a new starting key / note
What's New in Version 1.4.1
• Fixed incorrect scales when modes everywhere is turned off
• Corrected interval names displayed on the staff for minor scales
Customer Reviews
A big helper.
This is another shut up 'n buy it now app. It's very helpful for anybody wanting to understand music.
Do not buy this app
Go buy "Music Tool" and get the same useful but basic information for free.
Works well
Yes it probably should be a little cheaper but for five dollars I have a very convenient and clean reference with me. The scales play correctly as you change keys so that complaint seems to have been addressed in the update. I like it and would recommend it over the other "circle" apps I've seen.
