There are only 4 types of basslines
I found this video interesting....
Type 1 monorhythmic chord followers
- One consistent rhythm through out (1/4 note or 8th note) follows the chords, just plays the root.
- Good for "driving" the band.
- Can be done in a "bouncy" way too.
- Can be hypnotic for lower energy songs.
Type 2 - drum rhythm chord followers
- Rhythm follows the drums (particularly the bass) ... the notes chosen still follow the root of the chords.
Type 3 - mimic
- Synchronise with the lead instrument - e.g. play the same riff as the guitar or same riff as piano works for reinforcing and filling out a killer riff, giving a fatter sound.
- Works best when there is a killer riff.
Type 4 - bass solo
Bass does its own thing. Think flea, les claypool. Bass players whos work stands apart from the rest of the song.
