Leading to Morlacchi's Swiss Shepherd where there was scope for hair-raising running passages, overthe-top rubatos,
double-tonguing and steely breath control - another delightfully corny depiction of folk-hero William Tell.
For a while, Gwydion Brooke was uncertain about how he would be able to renew his relationship with the German Adler bassoon, on which, it had been noted, he was remarkably rapid at
double-tonguing and possessed of a sensuous style of vibrato.
The latter gives a sharply defined, more punctuated quality of articulation, whereas the earlier syllables produce passages `roundly, clearly and rollingly' (Tromlitz, who, in his endearingly pedantic manner, claims to have spent two hours a day for six months perfecting the subtlety of his
double-tonguing tad'llad'll).
