Huh?? was RE: pRCT got ears again...

[David Ilvedson]

  Here is the first part.   I'm going to try scan the pages and send as a attachment in the next day or so...    

        Order	 		Interval			Common Harmonic			Beats/Sec							Image of Beats
									      Pitch

1  Fundamental 37A tuned from A440 fork											Tempo=120 March>>>>>2 beats per sec
2  37A - 42D       	Upward 4th					61A						0.89			Slightly slower than 1 beat/sec.  Almost 1 beat/sec
3  35G - 42D		Downward 5th				54D					0.63			Slightly faster than 1 beat/sec.
4  35G - 40C		Upward 4th					59G					0.81			Slightly slower than A-D or same
5  33F - 40C		Downard 5th				52C						0.56			Same as D-G or not to be faster the D-G

CHECK
6  33F - 37A		Downward 3rd				51A					6.5, about 6			See to left

2 triplets and more in 1 second.   Imagine rhythm of               	                                                                                                                                                                                                                                                                                                                                               
march.  If this 3rd is slower than 6.5, needs less beats   s                                                                                                                                                                      somewhere in First step.  If 3rd is faster that 6.5, needs m                                                                                                                                                                     more beats somewhere in the First step				      	      

7  33F - 42D		Downward 6th				51A					           7.3			Make sure the beat of D is higher than pure point
