Beyond being merely exercises in alternate tunings, these are two works of contemplative beauty, and explorations of the "unearthly" timbres of tuned glasses.

Larry Polansky's Glass (1978-79) explores "heterophonic tunings": the gradual substitution of pitches from one harmonic series to another resulting in the simultaneous sounding of different and sometimes contrasting intonations.

In Hunter Coblentz's Lattice (2018), pitches relate to one another via "Just" relationships, spiralling ad infinitum through pitch space away from any intonational focus or key–the compositional approach composer Lou Harrison called "free style."
