Spectra Musica was formed in 1980 as an ensemble dedicated to the performance of early European music. They produce an average of three main programs a year of music from about 1400 to 1800 AD. The ensemble has grown to nine players and specializes in music for winds. Late Medieval and Renaissance music is performed with cornetti, kortholts, sackbuts, recorders, flute, rackett, dulcian, and viola da gamba, with a small Italian harpsichord as continuo. Baroque music is performed with period recorders, oboe, and flute, with gamba and a Flemish harpsichord as continuo. They perform extensively throughout the Philadelphia area, New Jersey, and Delaware. Sub-groups of two to four players are available to provide music for festive occasions. The musicians wear costumes, if requested, and play Renaissance music on authentic instruments of the period. Spectra Musica also provides lecture recitals and instrument demonstrations for those interested in learning about early musical instruments and the music written for them.
