How does mbira make sound?

The mbira, often referred to as a thumb piano, produces sound through the vibration of metal tines attached to a wooden soundboard. When the tines are plucked with the thumbs, they vibrate and create sound waves that resonate through the soundboard, amplifying the sound. The varying lengths and thicknesses of the tines produce different pitches, allowing for melodic and harmonic combinations. Additionally, the instrument may include resonators like gourd or metal tubes to enhance the sound further.
