Locke, Matthew
Ffor seaverall ffreinds: 54 pieces in 8 suites, for a treble and a bass instrument, possibly with basso continuo
GB-Lbl Add.ms. 17801 (autograph, 8 suites); GB-Lbl Add.ms. 33236 (8 suites with 2 pieces not included in the autograph); GB-Lbl Add.ms. 10444 and 10445 (8 suites); GB-Cfm MU.ms. 735 (8 suites with 2 pieces not included in the autograph); GB-Och ms. 409-410 (8 suites with 8 pieces not included in the autograph); GB-Lbl Add.ms. 31431 (4 suites with 1 piece not included in the autograph, treble part only); GB-Mc ms. A.2.6 (1 suite, bass part only); GB-Ob ms.mus.sch. C.44 (2 pieces)
Musica Britannica XXXI; Güntersberg
Harding groups these pieces not in 8, but in 12 suites, dividing them between those in minor and major modes.
The bass part contains a few figures, so performance with basso continuo is also intended.
None of the sources has an explicit instrumental indication, but instruments of the violin or the viol family would be most probable.
