Thanks to David Vanderlip of Pomona College for his outstanding retuning of the Steinway B grand piano to the scale shown below.

Below is the harmonic lattice of the above tuning showing the acoustically pure prime relations (as a counterexample, the interval from D to A is 40/27, not a perfect fifth 3/2):
C Db D Eb E F F# G Ab A Bb B
1/1 28/27 9/8 7/6 5/4 4/3 45/32 3/2 14/9 5/3 7/4 15/8
horizontal links are pure fifths (3:2), vertical links are pure major thirds (5:4), and diagonal links are pure harmonic sevenths (7:4).
