accelerando

This facilitates the accelerandi and ritenuti already mentioned and orientation in ensemble play.

While pieces from the 1970s and earlier are typically ametrical--with supple, ever-changing rhythmic configurations, grace notes, and accelerandi and ritardandi within a single beat--more recent pieces are just as likely to employ a constant underlying pulsation.

Robust features like TempoTap(TM) allow users to control the nuances of rubati, accelerandi, and ritardandi with the tap of a finger.

The sophistication of the band's playing extends to formal accelerandi built into the tune.

Its performance here showed the quality of the orchestra, but remained efficient rather than terrifying, staid, under-characterised, and with Vanska going for uncalled-for accelerandi rather than grinding awesome power.
