Eagle 53 Musical Tuning
 

Eagle 53 is a 12 notes per octave tuning designed to improve on, and replace,
the standard Western tuning: 12 Tone Equal Temperament. Some notes are higher
than usual and others are lower in varying degrees (see the frets in the photo
below). Eagle 53 has several advantages over the standard tuning: many
chords are more in tune and some new and exotic scales and chords occur.
The "53" refers to 53EDO (53 Equal Divisions of the Octave). Eagle 53 is
a 12 note subset of 53EDO. For a limited time my John's Rules Music
book is available free as a PDF. Click here to download it.

E53 fretboard


On Eagle 53 guitars (tuned EADGBE) the E major, E minor, F major, G major, G# minor, A major, A minor,
B major, B minor, C major, C# minor, and D# minor are all good and are more in tune than in the
standard tuning (12TET). There is a 4:5:8:10 chord available on F# (F#,A#, F#,A#) and on D (D, F#, D,F#).

All of these chords are all within 1.4 cents accuracy of just (pure), almost perfectly in tune.
A major chord looks like 2:3:4:5:6:8. A minor chord looks like 10:15:20:24:30:40

My own Credo Tuning (June 2012)
0.0, 116.129, 193.5484, 309.6774, 387.0968, 503.2258, 580.6452,
696.7742, 812.9032, 890.3226, 1006.4516, 1083.871, 1200.0.
This tuning is a 12 note subset of the 31 notes in 31EDO.  If a Major chord is defined as: 2:3:4:5:6:8
then the I Major, IV Major and V Major chords are all good (i.e. all the intervals that occur in the
major chords are within +/- 6.7758 cents accuracy). The I chord is on 0 cents, the IV
chord is on 503 cents and the V chord is on 697 cents.
