What tempo marking means very fast?
The Italian musical term "Presto" is generally used to indicate a very fast tempo for a piece of music. It is translated literally to mean "quickly" and is one of the most frequently used tempo markings.
Presto is characterized by a brisk and lively pace and conveys a feeling of urgency and speed. Other Italian tempo markings that denote very fast speeds include "Vivacissimo" (very lively) and "Allegrissimo" (extremely fast).
