I have had many requests for the overtone singing study guide and am in the process of making the it available again. I had only made 1000 copies. I am just sorting out the details now and will keep people posted as to progress. I am not sure whether it is better to make hard copies or just e-copies. Please let me know what the preference is.

Harmonic Chant is another popular name for Overtone Singing. By using the word ‘Chant’ it appeals to a slightly different audience associating it to Gregorian Chant and giving it a more spiritual context. However, this is mostly just marketing. Personally I see Overtone Singing as the generic overarching term for all such vocalisations that seperate the Fundamental from the Overtones audibly. Harmonic Chant is a subset preferred by certain artists such as David Hykes.

There is a technical difference as well which is that all harmonics are Overtones but not all overtones are harmonics. Harmonics are by definition  perfect whole number ratios of the fundamental frequency. Overtones can be distorted by physical anomalies such as tightness and thickness of a string.

A form of singing where a person uses the mouth cavity as a filter to seperate and amplify the individual overtones from the fundamental and rendering them audible as separate tones. There are many different traditional styles of overtone singing coming from different cultural groups such as the peoples of Tuva, Mongolia, South Africa, Inuit, as well as modern Western styles.

The common factor is that the singers can isolate the overtones and make separate melodies from the note(s) of the Fundamental.
