Curso de Teoria Musical - Aula 03: Campo Harmônico l Aula #44

Summary

In this lesson on musical theory, the instructor explains the concept of harmonic fields and their relationship with scales. By using examples such as the C major and A major scales, the lesson demonstrates how each scale generates specific chords—major, minor, and diminished—based on its degrees. The instructor highlights the importance of understanding harmonic fields for interpreting music and transcribing songs by ear. Practical tips and resources are provided, including access to the instructor's YouTube channel and website for additional lessons and free theory materials.

Takeaways

• 😀 The course focuses on music theory, covering topics like notes, intervals, scales, and harmonic fields.
• 😀 To understand advanced music theory concepts, one must first grasp the basics of notes, intervals, and scales.
• 😀 A note is a single sound, while a chord is a combination of multiple notes played together.
• 😀 A harmonic field (campo harmônico) consists of the chords that can be used in a piece of music based on its chosen scale or key.
• 😀 Different musical scales lead to different harmonic fields. Each of the 12 notes has its own corresponding scale and harmonic field.
• 😀 The first, fourth, and fifth degrees of a major scale form major chords, while the second, third, and sixth degrees form minor chords. The seventh degree forms a diminished chord.
• 😀 Understanding the harmonic field of a key makes it easier to compose and identify the chords in a song.
• 😀 For example, in the C major scale, the I, IV, and V chords are major, while the II, III, and VI chords are minor, and the VII chord is diminished.
• 😀 Harmonic fields help musicians anticipate what chords will appear in a song based on its key, greatly aiding in playing by ear.
• 😀 The speaker emphasizes that learning the rules of harmonic fields (such as the major scale degrees) is crucial for understanding music theory and ear training.
• 😀 The course will later cover how to play chords on the guitar and will offer free downloadable PDFs for further study on music theory.

Q & A

What is the main focus of this lesson?

The main focus of the lesson is on understanding harmonic fields and how they relate to chords in different keys, as well as reviewing basic music theory concepts such as notes, intervals, and scales.

How does the lesson differentiate between a note and a chord?

A note is an isolated sound (e.g., C), while a chord is a combination of multiple notes played together (e.g., a C chord).

What is a harmonic field?

A harmonic field is the set of chords that form the harmonic structure of a piece of music, and it is determined by the scale or key of the music.

How is a harmonic field constructed in the key of C major?

In the key of C major, the harmonic field is made up of major chords on the 1st, 4th, and 5th degrees (C, F, G), minor chords on the 2nd, 3rd, and 6th degrees (Dm, Em, Am), and a diminished chord on the 7th degree (Bdim).

What is the rule for determining major and minor chords in a key?

In any major scale, the 1st, 4th, and 5th degrees will form major chords, while the 2nd, 3rd, and 6th degrees will form minor chords. The 7th degree will typically form a diminished chord.

Can the harmonic field vary depending on the key?

Yes, the harmonic field will change depending on the key because each scale has a different set of notes, and therefore a different set of chords derived from those notes.

How does understanding the harmonic field help in transcribing or composing music?

Understanding the harmonic field makes it easier to predict which chords will appear in a song, making transcription and composition smoother. It helps identify the likely chord progressions based on the key of the music.

What does the instructor suggest about learning to play by ear?

The instructor suggests that understanding harmonic fields greatly aids in learning to play by ear, as it makes it easier to recognize the chords and progressions used in songs.

What is the significance of the 7th degree in the harmonic field?

The 7th degree of a scale always forms a diminished chord in the harmonic field, as it contains a minor seventh interval that gives it a tense, unresolved sound.

What resources does the instructor offer for further learning?

The instructor offers a free PDF music theory book on their website, which provides detailed explanations of music theory concepts, and suggests watching previous video lessons for additional learning.
