I see a lot of new Bassists that would appear to not really know what the main roll of the Bass is within a song.
It is not to shred all over the fret board and perform a myriad of solos and jump around on stage like an idiot, although you can find a lot of people that think this is the ultimate goal of playing Bass.
The proper place for the Bass is in the RHYTHM section of a band and keeps the beat and rhythm driving forward. The 6 string electric is in the LEAD section and performs the solos, arpeggios, acrobatics etc. If the lead guitar fumbles a couple of notes in a solo chances are most people will not notice BUT if the Bass fumbles the rhythm/timing the whole song falls apart.
I am new to Bass but not music and up until today I did not realize, and appreciate, how important the main roll of the Bass part was in a song until I came across this YouTube video that shows exactly how flat the sound can be without the Bass line. This is shown dramatically at 2:59 and 3:50 in the video.
This is my Ah-Ha moment for today and I thought others may appreciate it.
