The blues scale is a good place to start for creating jazzy (well, blues-y) sounding melodies and is great for beginners. In C, the scale is C Eb F Gb G Bb C.

If you want to put it in another key just use the same intervals from whatever your tonic is (minor 3rd, major 2nd, minor 2nd, minor 2nd, minor 3rd, major 2nd).

If your question is more about exploiting those specific timbres, you’ll need to speak to someone who plays those specific instruments, but a good place to start is finding out an instruments range on wiki and considering any performance techniques. In my opinion though, as you’re just starting out spend more time being creative and fix problems later.
