it is simple arpeggios with some melodic decoration to the sus4 for each chord except the last one, played with fingers or plectrum (I think plectrum but I can almost get the sound with just fingers
chords are B-F#-G#m-E (I-V-vi-IV)
pattern is B-B-D#-E-D#-F#-F#-A#-B-A#-G#-G#-C#-B-E-E-G#B-G#B- or similar G#B means play these two notes together
