Arcus cello bows are available in six different models:

Cadenza     Concerto     Sinfonia     Sonata     Allegro     Veloce

The models range from the Cadenza which produces an exquisite pure and projecting sound, and is used by international soloists, to the Veloce which produces a warm round sound and is preferred by students and amateurs. The Concerto, Sinfonia, and Sonata bows are used most by orchestral musicians and serious students and amateurs.

The Allegro is designed especially for those musicians who prefer the playing characteristics of the Veloce but need a better sound.

The Cadenza, Concerto, Sinfonia, and Sonata bows are available with either round or octagonal sticks. The Veloce and Allegro bows have round sticks. As a general rule, the octagonal sticks are a little more 'lively' than the round sticks. The weight of the cello bows is approx 70 gms for the professional bows, and 80 gms for the Allegro and Veloce.
