In music theory , harmonic rhythm , also known as harmonic tempo is the rate at which the Chord music chords change. According to Joseph Swain 2002 p.4 it is simply that perception of rhythm that depends on changes in aspects of harmony. According to Walter Piston 1944 , the rhythmic life contributed to music by means of the underlying changes of harmony. The pattern of the harmonic rhythm of a given piece of music, derived by noting the root chord root changes as they occur, reveals important and distinctive features affecting the Music genre style and Texture music texture . Harmonic rhythm is rarely notated or described exactly rather, analysts compare the overall pace of harmonic rhythm from one piece to another, or the amount of variation of harmonic rhythm within a piece. For example, a key stylistic difference between Baroque music and Classical music era Classical period music is that the latter exhibits much more variety of harmonic rhythm, even though the harmony itself is less complex. Alexander Scriabin s music features an increasingly slow harmonic rhythm beginning in his middle period.

Orphan date February 2009 The Harmonic scalpel is a cutting instrument used during surgical procedures to simultaneously cut and coagulate tissue. The Harmonic brand is manufactured and distributed by Ethicon Endo Surgery a subsidiary of Johnson & Johnson . The instrument is similar to a Bovie , but superior in that it can cut through thicker tissue, creates less smoke, and may offer greater precision. However, the harmonic scalpel is not as easily maneuverable as the Bovie, and takes longer to cut and coagulate tissue. Additionally, while a Bovie can be used to coagulate bleeding tissue at any time, the Harmonic scalpel only coagulates as it cuts. The Harmonic scalpel causes less lateral thermal damage than the Bovie . Whereas a Bovie performs its action via an electrical current and production of heat , the Harmonic scalpel cuts via vibration. The scalpel surface itself cuts through tissue by vibrating in the range of 55,500 Hz. The vibration cuts through the tissue and seals it using protein denaturization, rather than heat. A good analogy is whisking an egg white denaturation of the protein by vibration rather than heat.

Unreferenced date December 2009 To produce an artificial harmonic , a stringed instrument player holds down a note on the neck with the Handedness non dominant hand , thereby shortening the vibrational length of the string, uses a finger to lightly touch a point on the string that is an integer divisor of its vibrational length, and plucks or bow music bow s the side of the string that is closer to the bridge. This technique is used to produce harmonic tones that are otherwise inaccessible on the instrument. To guitar players, one variety of this technique is known as a pinch harmonic . This technique, like natural harmonics, works by canceling out the fundamental tone and one or more partial tones by deadening their modes of vibration. See node physics node .
