I have another problem. It seems that there are 2 commonly used numbering schemes for Haydn's Keyboard Sonatas. One goes from 1-47, and is used in the New Grove's, and on a new EMI CD I have. I don't know whether EMI is constistent in this practice. The other, apparently from the "Christa Landon Edition", numbers them 1-62. This scheme is used by R.E.D., Da Capo Catalogue, and on a new Hungaroton CD. Does anyone: a) have an idea as to which scheme is more commonly accepted; and/or b) prefer one scheme over another? Thanks *par usual* Bob K.
