Chord progressions. Cookie Cutter.
Drum Patterens and rudiments. Cookie Cutter.
Scales for melodies/improvisation. Cookie Cutter.
12 notes in the musical alphabet? Cookie cutter.
The cool part is you can learn all the cookie cutter shapes and try experimenting to bring your own twist to it. Many people do this by taking shapes from other musical styles and meshing them. Different instruments, different scales and different progressions help bring separation. Music Theory has a tendency of exposing the patterns in music for you to fit them in however you choose. The alphabet only has 26 letters, yet you can use those to say a lot. I'm sticking with Cookie Cutter. However you want to cut your cookies is fine.
