«Blue Canon» is a 3-in-1 Canon in G for Oboe, Recorder, Violin, and Continuo, tuned into Eagle 53, a tuning devised by John O'Sullivan. Eagle 53 is normally centred around E; for this piece the same tuning centred around G has been preferred, though. The tuning has the following cent figures: G= 0 113.2 203.8 317 384.9 498.1 588.7 701.9 815.1 883 1018.9 1086.8; essentially, when centred around G, it consists in three pieces of the pyhtagorean chain of fifths: from Fb to Db, from C to A, from G# to E#. It can be used in a more diatonic fashion though, by avoiding the use of triads on F and A. Anyway, this example has been notated by means of the 12-edo customary notation.
