How Do Xylophones Create Sound?
History of Xylophones
"In the seventeenth century, African instrumentalists took the xylophone with them to Central America where it was modified and became known as the marimba." Curt Sachs- How Products Are Made
• By striking the metal bars or wooden bars on the xylophone with a mallet or stick, it creates a vibration.
• This vibration is determined by the length of the bar which is below the actual bars to project the sound and sustain it.
• The longer bars create a deeper sound compared to the shorter bars.
• Air is pushed through the tubes creating more vibration as well.
• The xylophone is an incredibly old instrument.
• It is a part of the percussion section.
• This instrument originated in Africa and Asia around the 17th century.
• Originally made with wooden bars but xylophone makers struggled with trying to tune the bars.
• Xylophones became popular in Europe because of its use in folk music.
• Xylophones today use either wood or metal depending on the preference of the buyer.
