'''Valentine''' is a [[regular temperament]] that divides a tempered [[3/2]] into 9 equal [[generator]]s which are small semitones close to 78 cents; a stack of 3 generators is interpreted as [[8/7]] and a stack of 5 generators is interpreted as [[5/4]]. The generator serves as both [[21/20]] and [[25/24]]. It is a member of the [[starling temperaments]], by [[tempering out]] [[126/125]], and the [[gamelismic clan]], by tempering out [[1029/1024]]. It extends naturally to the [[11-limit]] by treating the generator as [[22/21]], tempering out [[121/120]], [[176/175]], [[385/384]], and [[441/440]].
 
Valentine can be viewed as a counterpart of [[miracle]] in several ways. Miracle splits the generator of [[slendric]] in two while valentine splits it in three. Miracle is generated by [[15/14]][[~]][[16/15]], the classical diatonic semitone tempered together with the septimal major semitone, while valentine is generated by 21/20~25/24, the classical chromatic semitone tempered together with the septimal minor semitone. Miracle is known for its efficiency; the same is true of valentine. The [[11-odd-limit]] [[tonality diamond]] is covered by miracle with 22 generator steps, and by valentine with 21 generator steps.
 
Valentine is very closely related to [[Carlos Alpha]], the rank-1 non-octave temperament of [[Wendy Carlos]], as the generator chain of valentine is the same thing as Carlos Alpha. Indeed, the way Carlos uses Alpha in ''Beauty in the Beast'' suggests that valentine might be a better description of Alpha than the rank-1 temperament that we know as Alpha today.<ref><i>Wendy Carlos</i>, Pitch article (1989) Accessed 2025. https://www.wendycarlos.com/resources/pitch.html</ref> Carlos tells us that "[t]he melodic motions of Alpha are amazingly exotic and fresh, like you've never heard before", and since Alpha lives inside valentine this comment carries over and applies to it if you stick close melodically to generator steps, which is almost impossible not to do since the generator step is so small. [[Mos scale]]s of 15, 16, 31 and 46 notes are available to explore these exotic and fresh melodies, or the less exotic ones you might cook up otherwise.
