| '''Blackcomb''' is a [[5/3]]-repeating [[regular temperament]] that tempers out [[250/243]] in the 5-limit, the amount by which three [[3/2]]'s exceed [[5/4]]. This implies a generator of a [[Blackwood]]-like sharp fifth which is quite "dirty" but still recognizable. It possesses [[MOS scale]]s of the form [[1L 3s (5/3-equivalent)|1L 3s<5/3>]], [[1L 4s (5/3-equivalent)|1L 4s<5/3>]], making it an antidiatonic tuning, [[5L 1s (5/3-equivalent)|5L 1s<5/3>]], and [[6L 5s (5/3-equivalent)|6L 5s<5/3>]]. [[16ed5/3]] is one of the best tunings for this temperament that is not extremely close to an EDO.

| Blackcomb is structured on 4:5:6 triads like octave-repeating [[meantone]] temperament. However, because Blackcomb is a much less accurate temperament, the major third and perfect fifth are usually tuned very sharp, with the major third often being closer to [[9/7]] than [[5/4]].
