how do you guys practice making up funk bass lines whether it is slap or fingerstyle. not to brag, but i am honestly an amazing slapper, just with no groove. my teacher describes it as "thrash punk slap" and i dont want that! i want catchy funky riffs. i notice that most slap bass lines that are slap are generally sparse and a lot of mutes. how can i practice this stuff more? can you suggest some songs too maybe?
