<HTML> Mr Bremmer, <P>Could you please explain the ratios given in the following paragraph? <BR>  <BLOCKQUOTE TYPE=CITE> <PRE>In the example you cited, if your Ab-C 3rd was slower than it should be, it    is very likely that your CE 3rd was much faster than it should be. This would    mean that your 4:5 ratio of contiguous 3rds was severly distorted.  Instead    of being 4:5 it may have been (from your description) something like 3:8.</PRE> </BLOCKQUOTE> Thanks, <P>Clark</HTML>
