I am slightly confused?!
Question: Are there two Rachmaninoff Op.33 no.8 etudes?
Answers: Are there two Rachmaninoff Op.33 no.8 etudes?
In a way, yes, Al, but it's a matter of numberings, not the identity of the work itself. Because certain of the études got suppressed by the composer at first, the numbering sequence of the physical items you can count, ends up out of step with the opus numbers attached to them: op. 33/9 in c# minor is the *eighth* item or 'number' in op. 33 as published now, while op.33/8 in g-minor, is the seventh item. Op.33/4 was suppressed by Rachmaninoff, and re-appeared as op.39/6 in the second set of Tableaux. It is this deletion that causes the item count and the opus number count to be out of step. In the first publication (1914) of op.33, only six items were included: op.33 nos 1,2,6,7,8,9. As mentioned, op.33/4 was later inserted into op.39, while op.33/3 and op.33/5 were only re-discovered in 1947, and published in 1948. With these two returned to their rightful places as originally envisaged, the op.33 set remains one short compared with the opus number assignments, which is where the notional anomaly comes from.
There is only one and it is in C# Minor
