Sona's passive name change

So, I really like the idea that each of Sona's power chords are called something different (i.e. Sona Q empowered passive is staccato). The problem is both the Q and the W are named after specific terms, whereas her E is simply named "Tempo." For the musically-challenged, tempo simply means how fast the piece is played. This is obviously related to how she slows down the enemy she basic attacks, but the implication of the word "Tempo" doesn't mean to slow down. This doesn't mean that I think that anyone would really get confused because of the name (I mean, nobody is gonna think that it'll speed up the enemy, that's ridiculous), but it does stand out. There are several alternatives. For instance, you can name the passive after a specific tempo marking (Lento comes to mind, Andante, or Largo), or it could be a marking that indicates that the piece is slowing down (Ritardando). It just makes more sense, you know.
