(Temporarily) clarify that this can be specified two ways. In the end it may entail distinct symbols for pitch relation and frequency ratio

Its full specification is (n-)ASp: (n pitches of an) [[ambitonal]] sequence adding by rational interval p. The n is optional. If not provided, the sequence is open-ended.
Its full specification is (''n''-)AS-''p'': (''n'' pitches of an) [[ambitonal]] sequence adding by rational interval ''p''.  
 
'''Note''':
* The ''n'' is optional. If not provided, the sequence is open-ended.
* The ''p'' can be dimensionless, in which case it refers to an interval by its [[frequency ratio]]. It can also take a unit proportional to [[octave]]s, in which case it refers to an interval by its pitch relation.

It is equivalent to a 1-dimensional [[Harmonic_Lattice_Diagram|JI lattice]] of p. These are sequences which are rational but ambiguous between otonality and utonality, such as a chain of the same JI pitch. It is also equivalent to an [[Equal-step_tuning#Equal_multiplications|equal multiplication]] of a rational interval p.
AS-''p'' is equivalent to a 1-dimensional [[Harmonic lattice diagram|JI lattice]] of ''p''.

The only difference between an (n-)ASp and an [[APS|(n-)APSp (arithmetic pitch sequence)]] is that the p for an AS must be rational.
