Abstract: Stemware of goblets secured in adjoining positions on a mounting board in vertical and horizontal rows, with adjacent goblets rim rubable by one hand, with the goblets in the horizontal rows arranged in tones for basic chords; for example, a first row in IV chord (subdominant), the next row is V.sub.7 chord (dominant) and the third row is I chord (tonic). The goblets are tuned by a partial filling of water, and the water level and the produced note are marked on the glass. The sounding board is marked for the positioning of the tuned goblets to permit the forming of the chords and easy playing by rim rubbing the stemware glasses.
