Como Descobrir o Tom da Música (Tabela Prática e Fácil de usar)

Summary

This video provides a comprehensive guide to understanding how to determine the key of a song using harmonic analysis. By analyzing chord progressions in relation to major and minor scales, the video explains how to identify both the theoretical key and tonal center of a song. The host demonstrates these concepts with examples from popular Brazilian songs, helping viewers understand how chords interact within a key and how to recognize the tonal center. The tutorial also touches on modal harmony and provides practical tips for beginners looking to deepen their music theory knowledge.

Takeaways

• 😀 Discovering the key of a song is not always straightforward, as the first chord doesn't always indicate the key.
• 🎶 The music's key can be determined by analyzing the chords and their relationship within the harmonic scale.
• 📊 A helpful tool for finding the key of a song is the harmonic table, which shows all the chords in major and minor scales.
• 🎸 A good method to identify the key is to arrange the chords in order of musical notes and check for patterns.
• 🧠 The presence of two consecutive minor chords suggests they are the second and third degrees in the scale, while consecutive major chords likely represent the fourth and fifth degrees.
• 🔄 The tonic, or tonal center, is the chord that creates a sense of returning to the starting point of the musical cycle.
• 🎹 In the example 'Apenas Mais Uma de Amor' by Lulu Santos, the song is in the key of F major, and its tonal center is F.
• 📌 'Tempo Perdido' by Legião Urbana starts with the C major chord, but its key is G major with a modal flavor of C major.
• 🎶 In some songs, like 'Malandragem' by Cássia Eller, even though the chords fit into the F major scale, the tonal center is the relative minor, D minor.
• 🎵 Harmony evolves over time, and as you learn more complex music, you will encounter songs with more intricate harmonic structures.

Q & A

What is the main focus of the video script?

The video script primarily focuses on teaching how to identify the key (tonal center) of a song using harmonic analysis and a harmonic table. It explains both major and minor keys, with examples from popular songs.

What is the importance of the harmonic table in identifying the key of a song?

The harmonic table is a tool that shows all the chords in both major and minor scales. It helps musicians map the chords in a song to their corresponding key, making it easier to identify the key by seeing if the chords fit within the major or minor harmonic scale.

How does the speaker suggest identifying the key of a song when the first chord doesn't match the key?

The speaker advises using the harmonic table to analyze the chords in the song and look for patterns, such as sequences of minor or major chords. The first chord might not always indicate the key, so it's important to look at the relationship of the chords and their progression to determine the tonal center.

What is the role of 'senso tonal' in identifying the key of a song?

'Senso tonal' refers to the sense of resolution or the feeling of returning to the tonal center of a song. Even if the song contains chords from different keys, the tonal center is often felt around the chord that provides this sense of resolution.

Can the key of a song be different from the first chord played? If so, how?

Yes, the key can be different from the first chord. The first chord might be a chord that leads into the actual tonal center of the song. This is common in modal music or songs where the tonal center is implied rather than directly stated at the beginning.

What example is given for a song that starts with a chord different from its key, and how is this analyzed?

The song 'Tempo Perdido' by Legião Urbana starts with the C chord, but the song is in the key of G major. The tonal center feels like C major, though, because of how the chords resolve. This is a case of modal music, where the song's tonal center isn't the same as the key derived from the chords.

What makes identifying the key of a song challenging when it comes to minor keys?

Identifying the key of a song in a minor key can be challenging because the tonal center may not always correspond directly to the first chord. Songs in minor keys may involve modal shifts, where the minor key feels like its relative major or another mode, making it more complex to analyze.

In the example of 'Malandragem' by Cássia Eller, how is the key determined?

In 'Malandragem,' the song contains chords that fit within the F major scale, but the tonal center is around the D minor chord, which is the relative minor of F major. Therefore, the key is F major with a D minor tonal center.

What are the benefits of using a harmonic table for beginners in music theory?

A harmonic table is particularly helpful for beginners as it provides a clear visual reference of all the chords in major and minor keys, making it easier to understand how chords relate to one another within a scale. It simplifies the process of identifying the key of a song and understanding its harmonic structure.

How does the speaker suggest analyzing songs for their key in a practical way?

The speaker suggests listening to the song, identifying the chords, and then arranging them according to the order of notes (C, Dm, F, etc.). By referencing these chords against the harmonic table, you can quickly determine which key the song is most likely in. Additionally, the speaker emphasizes the importance of the tonal center, or 'senso tonal,' for understanding the song's overall feel.
