A grace note is a kind of music notation used to denote several kinds of musical ornaments. When occurring by itself, a single grace note normally indicates the intention of either an appoggiatura or an acciaccatura. When they occur in groups, grace notes can be interpreted to indicate any of several different classes of ornamentation, depending on interpretation.

In notation a grace note is distinguished from a regular note by print size. A grace note is indicated by printing a note that is much smaller than a regular note, sometimes with a slash through the note stem (if two or more grace notes, there might be a slash through the note stem of the first note but not the subsequent grace note). The presence or absence of a slash through a note stem is often interpreted to indicate the intention of an acciaccatura or an appoggiatura, respectively.

The works of some composers, especially Frédéric Chopin, may contain long series of notes printed in the small type reserved for grace notes simply to show that the amount of time to be taken up by those notes as a whole unit is a subjective matter to be decided by the performer. Such a group of small printed notes may or may not have an accompanying principal note, and so may or may not be considered as grace notes in analysis.

Pat Torpey is an American rock and roll drummer, known as the drummer of the hard rock band Mr. Big. He has also played for Impellitteri, The Knack, David Lee Roth Band and the Exile Social Club.

Pat Torpey was born in Cleveland, Ohio on December 13, 1959. At age 7, he first played the drums. He tells the story: "I was at a family and friends picnic and there was a polka band. I was sitting on a railing behind the drummer and was fascinated at what I saw and heard. I went home and fashioned my own 'signature' drum sticks out of a fallen tree branch from our front yard".

In high school, Torpey immersed himself in all available music programs, concert, orchestra, marching and stage bands. About his teenage years, he says: "I wanted to play everything percussion and I convinced my mother to buy me a used drum-kit for my thirteenth birthday.” Torpey's family moved to Phoenix, where he then began honing his skills in local bands, from rock, to funk, to jazz, to pop.
