Glass Harp is a Youngstown, Ohio based power trio consisting of guitarist Phil Keaggy, drummer John Sferra and bassist Daniel Pecchio.

A glass harp (Glasharfein German ; also called musical glasses, singing glasses or the angelic organ) is an instrument made of upright wine glasses. It was created by Irishman Richard Pockrich, who is known as the first virtuoso of the musical glasses. It was popular in 18th century. We also know about the composer Christoph Willibald Gluck played the musical glasses also known as verrilion. He performed in London and Copenhagen. His instrument consisted of 26 goblets. It is played by running moistened or chalked fingers around the rim of the glasses. Each glass is tuned to a different pitch, either by grinding each goblet to the specified pitch, in which case the tuning is permanent, or by filling the glass with water until the desired pitch is achieved. The instrument has also been known by the names 'musical glasses' or 'ghost fiddle.'

Musical history was made on Saturday, February 18, 1979 by Gloria Parker performing as a musical glass or glass harp soloist with the Hartford Symphony Orchestra at the Jai-Lai Fronton in Hartford, CT. Richard Hayman, noted for his arrangements for Boston Pops conductor Arthur Fiedler, was the guest conductor for the 90-piece orchestra that accompanied the musical glasses which included Lara's Theme from the movie Dr. Zhivago, Lover and Amor.
