A physical point of view
The diagram below shows all tone pitches (marked in color) which I am able to play on channel #4 of one of my C-harps (both reeds oscillate, right half of the diagramm). I was also interested in the question which pitches are attainable with single reeds (all other reeds tightly taped, left half of the diagram).
The green lines mark the eigen frequencies of the reeds (plucked C, plucked D). Like on a tuning device there are no frequencies (in Hertz) specified, but differences in the perceived pitch (in cent). The reason is that we hear not only volume, but also frequencies "logarithmically". The origin (0ct = zero cent) can be arbitrarily chosen, in the diagramm 0ct corresponds to a normal blow note C. The difference between two seminotes is 100ct, so an octave sums up to 1200ct.
For channels #1 to #6 there would be similar diagrams and explanations. Channels #7 to #10 would require to switch the roles of blowing and drawing (for example blowbend instead of drawbend).
