It's an interval like a 5th, 10th, etc. Count the number of notes. Since we count the starting note (C-E is a 3rd, C-G is a 5th, C-C an 8th) a double octave is a 15th. Count it. dave Joe & Penny Goss wrote: > David, > How do you come up with a 15th being a double octave? > My thinking was that a 16 was a double octave. 1-2-4-8-16-etc > Joe Goss > ---------- > > From: David Porritt <dporritt@swbell.net> > > To: pianotech@ptg.org > > Subject: Re: Octave Stretch in other Lands > > Date: Saturday, March 06, 1999 8:19 AM > > > > Newton: > > > > A 15th is a double octave! > > > > dave > > > > -- > > _______________________________________________ > > > > David M.
