PETER WHITEHEAD is an instrument builder, performer, and composer. His singular instruments, often based on folk instruments from around the world, feature unusual found materials.
Among his many instruments are the Heart Banjo, made from a baking tin; the Lawn Lyre, made from an old lawnmower and a metal oil pan; and the Spoonharp, made from a five-gallon metal drum, a eucalyptus branch, and kitchen spoons.
Originally from England, Whitehead is now based in the San Francisco Bay Area. Founding member of the Mobius Operandi performance group, he also performs regularly with Closer To Carbon, an improvisational trio. Join Exploratorium staff Paul Doherty and Robyn Higdon as they discuss the Transit of Mercury. On November 8, 2006, Mercury slowly slid across the face of the sun during a relatively rare event known as a transit. The Exploratorium's Live@ crew was at the Kitt Peak National Observatory in Arizona to cover the event. This webcast includes a brief history of Kitt Peak and its 21 telescopes. At the age of eleven, Peter D'Amato ordered a Venus flytrap from Famous Monsters magazine; thus began a lifetime of cultivating carnivorous plants. His small apartment became an urban jungle, so he moved to Sebastopol, California, the home of California Carnivores, where he grows and sells hundreds of other-worldly plants whose traps range from those small enough to capture protozoa to those big enough to contain a rodent. Peter D'Amato of California Carnivores gives us a guided tour of the Venus Flytrap, one of the world's best-known carnivorous plants. If you’ve ever gone to hear an orchestra play, you know that the performance begins only after a session of tuning. An oft-repeated story tells of a visiting foreigner attending a concert in Paris. Afterwards, when asked which part of the performance he liked best, he replied, “The beginning, just before the man with the stick came in.”
Tuning means adjusting the pitch of an instrument. The pitch of a sound depends on its frequency, the number of vibrations per second that produce the sound. For example, plucking a cello string might cause it to vibrate back and forth 200 times each second. You hear that sound as a low pitch of 200 cycles per second, or 200 hertz.
An orchestra tunes itself to a very particular frequency, usually 440 hertz, a note known as A 440. The note is played by the oboist, and the rest of the orchestra tunes their instruments to match it. The oboe leads the tuning because of all the instruments, it is least affected by humidity or other weather conditions. Music is more than meets the ears directly. Just as no sound exists in a vacuum, every space sculpts the sound within it. Like a site-specific equalizer, reflections, absorption, and resonances combine to give each venue a unique acoustic stamp.
A subway tunnel is “live” space, rich with reverberations that trap and reflect sound in a well of hard tile. True to their name, “dead” spaces do nothing: The only sound heard is what travels directly from instrument to ear. An open field is the ultimate dead space.
As you follow this wandering riff, listen to the changes wrought by environment. Distance is also a factor here—the sound you hear is recorded from the camera’s vantage. Which spaces sound live? Which sound dead? Do the acoustic changes affect the feeling of the music?
Saxophonist Michael Pearce plays with the Highwater Blues Band in the San Francisco Bay Area. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week’s “secret” ingredient- carbohydrates! A series of sometimes fiery demonstrations shows what the pressure and composition of Venus’s atmosphere are like. This program was presented in conjunction with the Exploratorium’s webcast of the 2004 transit of Venus. Astronomers in many parts of the world watched as Venus moved across the disk of the Sun, one of the rarest planetary alignments. The Exploratorium webcast this historic event from Greece.
