Could you elaborate? I’m a music teacher and it checks out to me.
C4 up a 5th is G4, then up a fourth is C5. C4 to C5 is an octave.
Two octaves is a 15th. In music when the composer wants you play up an octave, they write (typically) 8va. When they want you to play up two octaves, they write (typically) 15va.
It is 2025, and we are talking about an election that is happening in 2028. The primary isn’t even on most people’s radar. If we can’t criticize candidates now, precisely when is it appropriate to level criticism at politicians???
