Harmonia Funcional aula 5 - DOMINANTES SUBSTITUTOS - Nelson Faria

Summary

Nelson Faria discusses dominant substitutes in music theory, explaining how they create tension and resolution. He uses the example of a tritone interval, which can be inverted without changing its resolution expectation. Faria shows how dominant substitutes can be used to create interesting harmonic effects and can be substituted for each other if they are a diminished fifth apart. He also touches on secondary dominants and their use in creating harmonic variety.

Takeaways

• 🎼 The script discusses the concept of dominant chords in music theory.
• 📚 It explains the dominant seventh chord and its role in creating tension and expectation for resolution.
• 🔄 The tritone interval, which is central to the dominant chord, can be inverted and still retains its characteristic tension.
• 👂 The listener's ear naturally wants to resolve the tension created by the dominant chord.
• 🎹 The dominant chord's tension can be resolved by moving to the tonic chord.
• 🤔 The concept is illustrated with an anecdote about a child playing the piano and the father's humorous reaction.
• 🎵 The script mentions the use of dominant substitutes, which are chords that can replace the dominant chord to create interesting harmonic effects.
• 🔄 Dominant substitutes can be a diminished fifth (or a half step) away from the original dominant chord.
• 🎶 Examples are given of how dominant substitutes can be used in different keys and in secondary dominants.
• 🎵 The script concludes with a demonstration of how dominant substitutes can be used in a piece of music.

Q & A

What is the main topic of Nelson Faria's discussion in the provided transcript?

The main topic of the discussion is about dominant substitutes in music, specifically focusing on the tritone interval and its role in creating a sense of resolution.

What is the significance of the tritone interval in music?

The tritone interval is significant because it creates an expectation of resolution. It is an interval that is inherently unstable and tends to resolve to a more stable chord.

Why is the tritone interval also called a 'dominant substitute'?

The tritone interval is called a 'dominant substitute' because it can replace the dominant chord in a progression, providing a similar sense of tension and resolution.

How does inverting the tritone interval affect its musical function?

Inverting the tritone interval does not change its musical function. It still creates the same sense of tension and expectation for resolution, regardless of whether it is played as a diminished fifth or an augmented fourth.

What is the relationship between the dominant chord and the tritone interval?

The dominant chord typically contains the tritone interval within it, which is why the tritone can function as a dominant substitute. The tension created by the tritone interval is what drives the need for resolution.

Can the dominant substitute be used in place of any dominant chord?

Yes, the dominant substitute can be used in place of any dominant chord, creating an interesting harmonic effect and adding variety to the music.

What is the role of the dominant substitute in a secondary dominant chord?

The dominant substitute can be used in a secondary dominant chord to create a smoother transition or to add a more complex harmonic texture to the music.

How does the concept of dominant substitutes apply to different keys or tonalities?

The concept of dominant substitutes applies to different keys or tonalities by using the tritone interval to create a dominant substitute that is a diminished fifth or an augmented fourth away from the original dominant chord.

What is the purpose of using dominant substitutes in music composition?

Using dominant substitutes in music composition adds harmonic interest and can create unexpected resolutions, which can enhance the emotional impact of the music.

Can you provide an example of how dominant substitutes are used in a specific musical piece mentioned in the transcript?

In the transcript, Nelson Faria refers to using dominant substitutes in various ways, such as in the song 'Minha Doce Namorada' where he uses a secondary dominant to create a smooth transition, and in 'Eu Te Amo, Te Amo, Te Amo' where he uses a dominant substitute to create a more complex harmonic texture.

What is the significance of the dominant substitute in the context of atonal music?

In atonal music, the dominant substitute, particularly the tritone interval, can create a sense of direction or tension even in the absence of a traditional tonal center, providing a structural element that guides the listener through the music.
