Porcupine is significant as a 5-limit temperament because it is the only 5-limit temperament other than meantone which possesses a 7-note MOS scale that is well-supplied with 5-limit major and minor triads (specifically, it has two of each of them). What is perhaps more significant about it is how naturally it extends those triads to involve the 11th harmonic; for instance, the first five consecutive notes of the Lssssss mode approximate the consecutive harmonics 8:9:10:11:12. This makes it a prime candidate for using extended JI-style harmonies in a compact and intuitive scale structure. | Porcupine is significant as a 5-limit temperament because it is the only 5-limit temperament other than meantone which possesses a 7-note MOS scale that is well-supplied with 5-limit major and minor triads (specifically, it has two of each of them).

Porcupine is a temperament completely capable of diverse harmony. Using it's MOS in conjunction with it's modmos will allow for some very diverse chordal movement that will still be tonally solid. Porcupine mode and modmos names are based on animal names because none of the scales remotely are similar to any existing mode name from anywhere. The initial four modes: Porcupine, Chinchilla, Zebra, and Dingo all contain 3/2 from the root while the latter three: Gazelle, Lemur, and Panda lack 3/2 and instead have a triad similar to a diminished triad on the root. In order to remedy this problem, it may be fruitful to use other methods than triadic tertian harmony to build tonal frameworks in porcupine. | Porcupine is a temperament completely capable of diverse harmony.

Because the generator of porcupine is 9/8, | Because the generator of porcupine is simultaneously 10/9, 11/10, and 12/11, a chord made up of consecutive generators approximates 9:10:11:12; since -6 generators approximates 9/8, the chord 8:9:10:11:12 can be approximated by a series of consecutive 2nds in the 7-note MOS. William Lynch considers varying subsets of 8:9:10:11:12 to work really well for building harmonic movement in porcupine. In addition, the second inversion which produces chords of stacked sevenths of varying sizes, also works well as an additional sonority to create better voice leading and variety. If the mode position of porcupine contains no 3/2 from the root, then a chord without 3/2 is played on the root. | ||
The MODMOS scales of porcupine can be used in conjunction with the regular MOS in order to build powerful tonal movement. While each useful MODMOS has it's own distinct name, they most likely will be useful to use as a particular function in each porcupine mode. They can also be used stand alone but little is known about the very complex system of tonality. | |||

The 7-note MOS of porcupine is great, but it lumps all the consonant chords together at one end of the scale (see below). It also fails to contain a complete 11-limit otonal hexad (4:5:6:7:9:11), even though porcupine is not excessively complex in the 11-limit. Thankfully, unlike in meantone[7] where the MODMOSs all reduce the number of consonant triads available, there are several MODMOSs of porcupine that contain an equal or greater number of consonant triads to the MOS (these are highlighted in blue text below). These MODMOSs also conveniently alter the distribution of triads within the scale, providing much-needed variety of possible chord progessions. Even better, some single-alteration MODMOSs make at least one full 11-limit hexad available, meaning 6 of the 7 notes of the scale can be sounded simultaneously and produce a consonant otonal harmony. The fact that porcupine temperament provides not just one 7-note scale but several that are equally-rich in harmonic resources makes it extremely fertile for modal harmony. | The 7-note MOS of porcupine is great, but it lumps all the consonant chords together at one end of the scale (see below).
