The orchestral piece St Thomas Wake ( 1969 ) uses many different styles of music , including foxtrots ( played by a twenties-style dance band ) , a pavan by John Bull and Davies 's own modern style .
The orchestral piece St Thomas Wake ( 1969 ) also shows this interest , and is a particularly obvious example of Davies 's polystylism , combining , as it does , a suite of foxtrots ( played by a twenties-style dance band ) , a pavane by John Bull and Davies 's `` own '' music ( the work is described by Davies as a `` Foxtrot for orchestra on a pavan by John Bull '' ) .
