When you are listening classical songs and you hear that beautiful arpeggios making mayor and minor chords, you start to imagine how to play it in your bass; there are many ways to get the arpeggios, but I like to show you an easy way to play and practice with your tapping technique.

Here is the cake!
To make it easy, what I do is to use my 1st and 3th right hand fingers to touch the 1st and 5th note respectively, and my 1st left hand finger to touch the 3th note. That's in the mayor and minor chords.
In the 1st, 5th, and 8th chords what I do to get the sound is to touch 1st note with my 1st left hand finger, the 5th and 8th notes whit my 1st and 2nd right hand fingers respectively.

With that in mind you can add cool variations to your classical tapping lines.

Got the idea?
