I would like to play the drums with a 5 piece kits because I feel like I miss one important tom with a 4 piece kit, especially for the Jack Dejohnette trio stuff. But I won't spend a dime on that, I'll just have fun playing with 2 toms and live with it.
Some people say that the Hi hat can be considered as a cymbal. Professor Auspicious is developing something weird right now as I only practice music with insulated headphones against recording like some sort of Autistic behavior. Bill Evans, Oscar Peterson, recently I added Keith Jarrett Trio, and the Miles of course.
It involved a load of drummers using various cymbals, I now use 3 different rides depending of the tune and they are all installed to my right just like in the picture of post #2. My 22" which sounds great against the recordings of jack Dejohnette (and other things), My 20" light flat which is really a soft all rounder with Bill Evans (and many other things) and my 19" Turkish crash ride which often go well with the recordings of Marty morel and Philly Joe occasionally in old albums.
I have my 17" low pitched crash to my left which is a cool crash
So 4 drums, 4 cymbals: 1 crash, 2 rides, 1 crash ride + 1 hi hat! Honestly I use both sides of the hi hat to get various sounds so they might be considered a cymbal after all. I love the bells on my 13" hats. K custom dark hats, I totally love them, they are so sweet and mellow, with a higher pitch against my low pitched cymbals.
I really love these sounds, damn.
