[ Pendulum Effect ] Your opponent cannot activate a Spell/Trap Card, or monster effect, when your "Solfachord" Pendulum Monster(s) is Pendulum Summoned. [ Monster Effect ] While you have an odd Pendulum Scale in your Pendulum Zone, if your "Solfachord" Pendulum Monster attacks, your opponent cannot activate Spell/Trap Cards or effects until the end of the Damage Step. During your Main Phase: You can Tribute 1 "Solfachord" Pendulum Monster (even if face-down), and if you do, Special Summon 1 "Solfachord" Pendulum Monster from your Deck whose Pendulum Scale is 2 higher or 2 lower than that monster, except "LaSolfachord Angelia". You can only use this effect of "LaSolfachord Angelia" once per turn.
