This is one of our favourites… strangely pentatonic.
Lots of clear triads in the upper register here with a weird Cm7 harmony
interesting cluster / augmented octave in the lower range and nice harmony at the upper end
This is the same fingering for the top E but underblown
A nice major second dyad in this one, plus a difference tone that comes out when in the upper register.
Broken octaves - arpeggio works very well
