The middle note comes from much higher in the overtone series.
Until the end of the 19th century, tuning of their partials (component tones in the overtone series) was not seriously undertaken and so lacked uniformity.
Because it enables keyboard instruments to play in all keys with minimal flaws in intonation, equal temperament replaced earlier tuning systems that were based on acoustically pure intervals, that is, intervals that occur naturally in the overtone series.
Without recourse to valves, hornists are most at home in the relatively few notes in the overtone series that come naturally to a bit of coiled metal: mainly, the notes you hear in hunting and military calls.
All three bands on the bill — Blonde Redhead, the Raveonettes and School of Seven Bells — enveloped their songs in the overtone haze of reverb, the better to conjure grand, mysterious, incantatory recesses in simple structures.
All these instruments produce sounds in the overtone series only (think of taps or reveille): in the lower spectrum of sound, the notes are an octave apart; the notes come closer together the higher the instrument is played.
Interestingly this photodissociation could be directly followed by RR spectroscopy in the overtone region as clearly as the fundamental region.
The overtone of this marker band for oxyHb band is observed at 3277 cm−1 and is not observed in the overtone region of deoxyHb.
The manband in question, the Overtones, are both dull as dishwater and half as attractive in total as the cleft in Gary Barlow's chin, but they do add a layer of crapulous doowop harmony that really does make everything better.
An important insight at this stage is that, in order to describe the overtones reported in this paper or asymmetric vibrational modes in general, it is imperative to include both σ- and π-orbitals in the model.
