OR - you could block out Draw 3 so that the 3rd
(B) does not clash with the 11th (C blow note),
and get true 11th and 13th chords. If a single
hole block of Hole 3 is too tiny, then play 1 and
2 draw (or just 2 draw), block out 3 and 4, and
play Draw 5 to give you a 7th. Then let the upper
blow chord run free.

Again, you could go for a full Major 11th by
blocking out any Blow E note that would clash.
You could play Blow 1, 3 and 4, or 3,4 and 6.

One thing about air recirculation is that you
need a good push from the main notes played, so
that there is enough air in circulation to get
the secondary reeds to sound. A full three or
four note chord played nice and loud will do it,
but for some of these trickier chords, like
clash-free 11ths, it may take some experimenting
with partly-blocked chords to find a combination
- - and an attack - that will motivate the
secondary reeds.
