|Unison Bend Tutorial|
The difference between simple bend and unison bend is
that unison bend begins with playing two notes simultaneously,
one note is to be lifted as to regular bend performance
and other one is a stable note (no bending).
So when the bend note is lifted both notes begin having same
frequency (hearing unison effect).

stable note should be one tone higher than bend note.
