is simandl book for just arco playing or for jazz players as well? also i have ray brown bass method and improvisers bass method by chuck sher. are these good books? reason why i have all these books is cause right now i .... DONT HAVE A TEACHER. BUT! i have had a teacher, i learned some fundamentals, so i dont think i am ingraining any bad habits (i am staying away from the bow right now for this reason, but pizz i know how to do). does that sound alright. also i'm gonna get a teacher but right now i dont have a place to practice my bass so i only play it like maybe once a week but once i get a new place and some time to practice i'm gonna go back to lessons.
