Mon (emblem) are not recognized by law. One of the best known examples of a "mon" serving as a corporate logo is that of Mitsubishi, a name meaning "three lozenges" (occasionally translated as "three buffalo nuts"), which are represented as rhombuses. Another example of corporate use is the logo for the famous soy sauce maker Kikkoman, which uses the family "mon" of the founder, and finally, the logo of music instrument/equipment and motorcycle builder Yamaha, which shows three tuning forks interlocked into the shape of a capital "Y" in reference to both their name and the origin of the company.

Augmented-fourths tuning lefty-righty symmetry. These properties characterize augmented-fourths tunings among non-trivial tunings. The set of augmented-fourths tunings has three properties that simplify learning by beginners and improvisation by experts: Regular intervals, string repetition, and lefty-righty symmetry. Besides the set of augmented-fourths tuning, exactly one other set of tunings has these three properties—the "trivial" class of one-note tunings, which contains the C-C-C-C-C-C tuning, for example. Augmented-fourths tunings have extended range. Because each of its tritone-intervals between successive strings is wider than the perfect-fourth intervals (and one major third) of standard tuning, augmented-fourths tunings have greater range than standard tuning—six additional notes, only one
