Question about Beats During Tuning

[Andrew & Rebeca Anderson]

Robert,
Earplugs help to focus you on what you want to hear.  The canal caps sold 
by Diane Hofsteter (dpno2ur@yahoo.com) are ideal and will protect your 
hearing over the long term.  The Music ear plugs sold in you local drug 
store are inferior (attenuate unevenly, too much high up) but will do as 
you start out.
A Coleman Beat Counter is good to help with the learning.  It will show you 
where to listen for a given interval.  Each note, like a beam of light, is 
made up of a symphony of partials.  With practice you will begin to use 
your ear as a prism to split out the coincident partials you are wanting to 
tune or count.   Say, for example, you want to practice tuning a 4:2 
octave, and you are tuning C5 to C4, tap C6 and then listen at that 
frequency as you play C4 & C5 together.  You will then hear the beat you 
are using to tune that specific type of interval.
Typically I don't count thirds and sixths.  I just "feel" when they are 
right and that they progressively speed up as I proceed up the middle of 
the keyboard.  There are a variety of tests that can help you arrive at 
good relationships between intervals.

What course are you taking?

Good luck,
Andrew
