Is a Plectrum used with a lyre?

Yes, a plectrum can be used with a lyre. Traditionally, lyres were played by plucking the strings with the fingers, but a plectrum, which is a small, flat tool used to strike or pluck strings, can also be employed to produce a different tone or volume. While not as common as finger playing, using a plectrum can enhance the sound and technique of the performance.
