regals

noun

1. 1.A small, portable organ whose sound is produced by beating reeds without amplifying resonators. Its tone is keen and rich in harmonics. The regal was common in the sixteenth and seventeenth centuries; today it has been revived for the performance of music from those times.
2. 2.An organ stop of the reed family, furnished with a normal beating reed, but whose resonator is a fraction of its natural length. In the sixteenth and seventeenth centuries these stops took a multitude of forms. Today only one survives that is of universal currency, the so-called Vox Humana.
