Allegro non troppo意思

"Allegro non troppo" is a musical term that means "fast, not too much." It is an Italian phrase used to indicate the tempo (speed) and dynamics (loudness) of a piece of music. The word "allegro" generally means fast, lively, or cheerful, and is one of the most common tempo indications in music. The addition of "non troppo" (not too much) modifies the instruction, suggesting that the music should be played at a fast pace, but not as fast as the unqualified "allegro."

Here's a breakdown of the terms:

• "Allegro": A tempo marking that indicates a fast and lively speed. It is one of the most common tempo indications in music and is often used as a default fast tempo when no other speed is specified.
• "non troppo": An Italian phrase meaning "not too much." It is used to modify other musical instructions, such as tempo, dynamics, or character, to indicate that the performer should not exaggerate the quality indicated.

When combined, "Allegro non troppo" tells the musician to play the piece at a fast pace, but not so fast that it becomes rushed or out of control. The exact speed can vary depending on the context of the piece and the interpretation of the performer or conductor.
