Frappare

Frappare is a musical term that refers to the action of damping or muffling the tone of a stringed instrument, particularly the violin, during a vibrato. It is achieved by rapidly pressing the finger on the string in a manner that alters its vibration, resulting in a decrease in amplitude and a change in timbre. This technique is often employed to create a muffled or subdued sound, and is commonly used in various musical styles, including classical and baroque music.

Frappare is typically applied to open notes, whereas the palmar annotation (fingernail) touches the string where the finger is placed. The finger is then briefly lifted, releasing the note and creating a small harmonic that enriches the tone of the note. This technique is often used in conjunction with vibrato, glissando, and portamento, allowing for a richer and more expressive sound.

There are two primary types of frappare: piano and forte. Piano frappare involves applying gentle pressure with the finger, producing a soft and muffled sound. Forte frappare, on the other hand, involves applying more pressure, resulting in a louder and more intense sound. The choice between these two types depends on the style of playing and the desired overall effect.

Frappare requires great precision and control, as the application of too much pressure can lead to a loss of pitch or an unwanted change in timbre. Hence, it is not recommended for less experienced musicians, as it may be too complex or tricky to master.
