Press keys 3, 4, 5, 6, 7, 8 or 9 to play beatless chords that occur in Eagle 53.

Pressing key 'o' will play chords in random order.

*******

Try holding down the 'o' key continuously. If no chords can be heard your key repeat rate is too fast...
On a Mac go to Apple Menu>>System Preferences>>Keyboard and slow down the key repeat rate there.
On a PC go to Start and search for "Control Panel" to slow down the keyboard key repeat rate.

The root notes in all of the chords pair nicely with each other, melodically,
meaning all progressions should be acceptable (JRM loose). All of the intervals in all of
the chords are within 0.1 cents of just. Each chord looks like 2:3:4:6:8
The root notes of the chords correspond closely to the 3:4:5:6:7:8:9 scale.
Either F chord (4 or 8) functions as a tonic or point of rest. All of the chords conform to the Eagle 53 tuning.

Here are the chords used...

3 - C  -498.1c (3/4)
4 - F        0.0c (1/1)
5 - A   384.9c (5/4)
6 - C   701.9c (3/2)
7 - D# 973.6c (7/4)
8 - F  1200.0c (2/1)
9 - G 1403.8c (9/4)
