Cristal baschet
The Cristal Baschet is an acoustic musical instrument belonging to the friction idiophone class. The vibration of its individual elements produces tones by means of friction.
== Operation ==
Metal rods are embedded in a heavy plate to form the elements. Each metal rod is accompanied by an attached glass rod. The metal rod's length, weight and position at the equilibrium point determine the sound's pitch. The glass rod is gently stroked with a wet finger to produce sound.
The vibration of the rod with greater amplitude and weaker pressure is transmitted into the metal fitting. This causes a transformation in the vibrations and the shape of the wave produced. The vibrations propagating through the metal have a high pressure and a weak amplitude. This amplification in pressure is the result of fiberglass cones that are fixed in a wood frame alongside a tall, cut-out metal part in the shape of a flame. "Whiskers," placed on the side of the instrument, amplify high-pitched sounds.
The Cristal Baschet is also known as the Crystal Organ and the Crystal Baschet. The range of a concert instrument is 5 octaves. The Cristal is unrelated to the glass harmonica.
