Is there any thumb rule that is applied when playing 3 string arpeggios with regard to fingering pattern? For example if I play B diminished arpeggio (3rd string - 10 fret, 2nd string - 12th fret, 1st string - 10th and 13th frets) should I be using the first and second fingers for the 3rd and 2nd strings OR should I be using first and third fingers OR It does not make a difference?
