polyphonic overtone singing - explained visually by Anna-Maria Hefele

Summary

Anna Maria introduces the technique of overtone singing, where a single person can produce two distinct notes simultaneously. She explains how the human voice naturally sings multiple tones, and with overtone singing, one can isolate and amplify a specific overtone. Anna demonstrates different polyphonic singing methods, including moving the fundamental and overtone in parallel or opposite directions, and how these techniques can be used to create harmonious melodies. She also mentions the use of 'Overtone Analyzer' software as a learning tool for overtone singers.

Takeaways

• 🎶 Anna Maria is an overtone singer, showcasing the technique of polyphonic singing where one person can sing two notes simultaneously.
• 🔊 Overtone singing is a voice technique that allows the production of multiple tones, including the fundamental and overtones, which are usually perceived as one single tone.
• 📊 A spectrogram is used to visually represent the voice, demonstrating the presence of multiple tones when singing a melody.
• 🎵 Overtone singers can isolate and amplify specific overtones by manipulating their vocal techniques, without the need for computerized frequency filters.
• 🎹 The basic concept of overtone singing involves making one of the overtones so loud that it is heard as a separate tone.
• 🎧 Advanced overtone singing techniques include moving the fundamental and the overtone in parallel, using different intervals to create complex melodies.
• 🔄 The fundamental can be moved in steps, creating a melody that alternates between tones, forming intervals such as a perfect fourth.
• 🎼 Overtone and fundamental can move in opposite directions, creating a major scale and demonstrating the versatility of overtone singing.
• 🦊 Anna Maria uses overtone singing to mimic the melodies of fox songs, harmonizing the overtones with the fundamental to create a polyphonic effect.
• 💻 The video features the use of 'Overtone Analyzer' software, a tool specifically designed for overtone singers to analyze and practice their singing techniques.

Q & A

What is overtone singing?

Overtone singing is a voice technique where one person sings two notes at the same time, producing a fundamental tone and its overtones.

How does overtone singing work?

Overtone singing works by filtering out unwanted overtones with the mouth, amplifying one overtone to make it loud enough to be heard as a separate note.

What is a spectrogram and how is it used in the demonstration?

A spectrogram is a visual representation of sound frequencies over time. In the demonstration, it is used to show the different tones produced while singing, including the fundamental and the overtones.

How can one practice overtone singing without a computer?

One can practice overtone singing without a computer by using techniques that involve controlling the mouth and vocal tract to filter and amplify specific overtones.

What is the difference between moving the overtone and moving the fundamental?

Moving the overtone involves changing the specific overtone that is amplified, while moving the fundamental changes the base pitch from which the overtones are derived.

What is the undertone scale and how does it relate to overtone singing?

The undertone scale is a series of fundamentals that have the original tone as one of its overtones. It is related to overtone singing as it provides another way to build scales and harmonize with the melody.

How can one create polyphonic singing with overtone techniques?

Polyphonic singing can be created by moving the overtone and the fundamental in parallel, using different intervals, or moving the fundamental in steps while the overtone follows the melody.

What tools does Anna Maria use to demonstrate her overtone singing?

Anna Maria uses a software called Overton Analyzer, which is a learning tool specifically created for overtone singers to visualize and practice their techniques.

How does Anna Maria demonstrate the separation of overtone and fundamental melodies?

Anna Maria uses frequency filters in the Overton Analyzer software to isolate and demonstrate the overtone and fundamental melodies separately.

What is the purpose of the Overton Analyzer software mentioned in the script?

The Overton Analyzer software is designed to help overtone singers visualize their voice and practice techniques by showing the different frequencies and overtones produced.
