Porcupine notation can be based on the Porcupine[7] Lssssss scale using standard notation. By representing the 3|3 mode (sssLsss) with D E F G A B C D and using sharps and flats (#/b) to represent a step up or down respectively, 15edo can be notated in a similar fashion to the diatonic scale. Its intervals can likewise be named with respect to diatonic intervals.

One neat thing about using this notation system is that its notated major scale, D E F# G A B C# D, directly corresponds to 15edo’s LH Nice-Ionian scale.

Porcupine notation can also be based on the porcupine[8] LLLLLLLs scale using eight nominals: α β χ δ ε φ γ η. Others have proposed ABCDEFGHA, but conflicts with european notation have caused many to reject this approach. Thus greek letters can be used in their place with a close resemblance to the spelling of ABCDEFGHA. The letters are not in greek alphabetic order.
