RUSH is THE PERFECT EXAMPLE of the fluidity of MASTERING TIME SIGNATURES! I play drums and there are a few things that you need to know about Neil Peart’s ( pronounced PEER-T) character: First he writes the lyrics so he knows in advance what TYPE of song it’s meant to be ie ballad, driver, etc. Second he COMPOSES on the drums… like a carpenter who looks at a set of blueprints before building the object. Neil lays out a SKETCH in his mind of the VOICES of the drumset and builds the song from there. He is also a great LISTENER knowing when NOT to step over Geddy’s singing or Alex’s solos! Finally, he had perfect timing and fluidity of time changes. He said himself that it’s not about COUNTING the time signatures as much as fluid motion to change the tempo without counting: in other words it should FLOW! He hates repeating the same drum patterns in the same song meaning if he plays a fill one way the first time around he will play it differently the second time around. IE. Rolls down the toms the first time around and triplets or quads (all four limbs) the second time around. In short there will NEVER be another like him on planet earth 🌍 🌏 🌎! REST IN PEACE PROFESSOR! With heart felt admiration and sincerity! Gary
