glass harp

plural glass harps

1. A musical instrument consisting of glasses (typically wine glasses) tuned by putting different amounts of liquid into them. Sound is produced by rubbing one's fingers around the rims of the glasses, causing them to vibrate.

   A newer glass instrument is the glass harp [G[erman] Glasharfe] constructed by B[runo] Hoffmann in 1929. Similar to the musical glasses of England, it consists of 46 individually tuned glasses fixed on a resonant table.

   Glass harmonicas are basically of two types. One type employs vertical wine glasses arranged so that the performer can rub more than one glass at a time. A collection of glasses played in this manner is sometimes called a glass harp. The other type, called the armonica by its inventor Benjamin Franklin, employs glass bowls or cups turned by a horizontal axle, so the performer need only touch the rims of the bowls as they rotate to set them into vibration[…].

   The glass harp produces the "sound of the universe" according to [Johann Wolfgang von] Goethe. The musician [Christoph Willibald] Gluck gave an entire concert using the glass harp in London in 1746. Sound is made when a wine glass "sings": run your finger around the rim. The sound is thus produced by making the glass vibrate rather than by making the air in the container vibrate (like blowing over a bottle).

   Joni [Mitchell] and Neil [Young] have both used alien and spaceman imagery to articulate their feelings, in interviews as well as in their lyrics. Listen to the words for Young's "After the Gold Rush" (1970) and you will hear a whole story of humanity's next exodus into space, a tale that prompted Linda Ronstadt, who covered the tune with glass harps, to say: "I would think, 'This is the future. Neil's humans leave the planet and go off to start a new space colony.' I've always felt Neil had a great deal of really uncanny prescience in his writing."
