Subj: [kl] strange intonation in warm up exercise
Date: Mon, 5 Feb 2001 19:02:37 -0500

A while ago someone posted some really nice warm ups. The first one was:
Tuner sounding on low written E, then play to it: tonic, dominant,
octave, subdominant, tonic in half notes, 60 to the quarter. Repeat
going up in half-tone steps for the entire octave. I'm sorry, I can't
remember who it was.

I don't have a tuner (anymore) which emits a sound but I've tried this
with pupils. I am the "tuner" i.e. I hold the first tone. The pupil
plays the sequence.

Recently I tried this whilst watching the tuner. What the tuner does is
rather strange. Can anyone explain it?

1) When the pupil plays the sequence, the tuner indicates the tone that
I am playing the whole time except for the subdominant although we are
both playing approx. the same dynamic and approx. the same distance from
the tuner. Why would the tuner only indicate the higher note when it is
the subdominant? Why not always? Or never?

2) At the dominant and subdominant, the needle tends to dip maybe four
our five cents (with the tuner still indicating the tonic). Since the
lower note is indicated and I'm pretty sure I'm not changing why does
the needle dip? Does this have anything to do with harmonicity? Does
anybody know?
