  1. L14Vibrating Air Columns, Organs, and Flutes

  2. Flute

  3. CT 3.4.2 What's the function of finger holes in a flute? • To create an edgetone • To shorten or lengthen the pipe • Emphasizes the affects of the reed • Mostly aesthetic • More than one of these

  4. Recorder

  5. Pan Pipes

  6. CT12.1.4b A flute playing its lowest note is shown in spectrum “A”. f1 refers to the fundamental of the flute. Which spectrum best matches a panpipe half as long as the flute? B A amplitude amplitude f1,flute f1,flute 6f1 6f1 C amplitude D amplitude f1.flute 6f1 f1,flute 6f1 E) None of these looks right.

  7. CT12.1.4b A flute playing its lowest note is shown in spectrum “A”. f1 refers to the fundamental of the flute. Which spectrum best matches a panpipe (of equal length) playing its lowest note? B A amplitude amplitude f1,flute f1,flute 6f1 6f1 C amplitude D amplitude f1.flute 6f1 f1,flute 6f1 E) None of these looks right.

  8. Organ

  9. CT 3.4.3 If we halve the length of a tube in a wind instrument what will happen? • The period is halved • The frequency is doubled • Raises the pitch one octave • Both a and b • a, b, and c

  10. CT 12.1.2 If you double the diameter of a long organ pipe, what happens to the fundamental you hear? • Goes down by an octave • Goes down, but way less than an octave • Goes up, by an octave • Goes up, but way less than an octave • Something else
