stringed instrument
A Japanese musician plucking the strings of a koto with the right hand to generate a pitch and pressing the strings with the left hand to alter the tone.
While both the lyre and the harp are chordophones, they are distinct instruments categorized by their construction and the orientation of their strings relative to the soundboard.1
Key Differences
- Structural Design: A lyre is defined by a yoke consisting of two arms and a crossbar that project from the body of the instrument. In contrast, a harp is characterized by a resonator, a neck, and—in the case of a frame harp—a pillar that creates a triangular structure.234
- String Orientation: The most significant technical distinction is that the plane of a harp's strings lies perpendicular to the plane of its soundboard. In a lyre, the strings extend from a crossbar over the belly (soundboard) and are generally parallel to it.423
- Playing Technique: On a lyre, strings are typically not stopped; they vibrate throughout their entire length when plucked. Harps, depending on their specific design and tradition, utilize a variety of plucking techniques, often involving strings of uneven lengths.34
While both instruments have ancient origins, they represent different evolutionary paths in the history of stringed instruments.1
