Introduction

In this video, the host attempts to explain what a major scale is to an alien visitor from another planet. The host explores different approaches to explaining the concept of a major scale and breaks down the theoretical structures behind it.

Defining the Major Scale

The major scale is defined as the major scale, also known as the ionian mode.

The host struggles to explain what a major scale is when put on the spot by his friend Nate Holder.

Explaining with Sound

One way to explain what a major scale is would be to play it for someone or show them songs that use it.

However, this approach doesn't work for someone who can't hear music, like an alien visitor.

Harmonic Construction

Another approach is harmonic construction, which involves defining the quality of chords in order to build a scale.

The host defines the major scale as having I, IV, and V chords that are all major triads.

Intervallic Construction

Intervallic construction involves using intervals to define a scale. The major scale has all major and perfect intervals.

This approach doesn't answer why these intervals are used in constructing scales.

Conclusion

While there are different ways of explaining what a major scale is, ultimately it comes down to understanding its sonic and musical implications within Western music theory.

Final Thoughts

Understanding what a major scale is requires familiarity with Western music theory and its terminology.

The Major Scale: Why We Use Seven Notes

In this section, the speaker explains how the major scale is constructed and why certain notes are included or excluded.

Consonance and Dissonance in the Major Scale

The major 7th is acoustically dissonant while the perfect 4th is contextually dissonant.

The perfect 4th sounds pleasant when played alone but creates tension when played in a major scale context with a major 3rd.

The major 7th is used to protect the tonality of the scale even though it's less consonant than the minor 7th.

Creating Tension and Motion in the Major Scale

Adding back in these two dissonant notes (major 7th and perfect 4th) creates a more active cycle of tension and release.

These two notes resolve in opposite directions, giving the major scale a balanced sense of directionality.

Choosing these two specific notes to drive the scale's tension allows for much more dynamic motion, with notes resolving in both directions, often at the same time.

What Is a Scale?

In this section, the speaker explains what a musical scale is and how it functions within music.

Defining a Musical Scale

A musical scale is an ordered collection of notes that implies hierarchy, with certain notes sounding more important than others.

Each pitch within a scale carries its own implied function, behavior, and character.

The most important note in any scale is the root or tonic, which serves as the foundation for the rest of the scale.

Challenges in Understanding Scales

Not everyone uses Western notation systems to write down music, and some people may not have any way of writing down music at all.

Even if you understand how a scale is constructed, there are still many other factors that go into creating a piece of music.

Understanding the Major Scale

In this section, we learn about the major scale and its functions. We also discuss how notes in a scale can be stable or unstable.

The Function of Notes in the Major Scale

The major scale has stable and unstable notes.

Stable notes are those that provide a foundation for complex structures while unstable notes create tension and release.

The 4th and 7th degrees of the major scale are dissonant but resolve to very stable tones.

The root, 3rd, and 5th degrees of the major scale are already pretty stable while the 2nd and 6th degrees can play both roles.

Understanding Pitch Perception

Most musical structures in Western music aren't based on absolute pitch but rather relative pitch perception.

Human pitch perception is mostly relative as we hear relationships between notes more clearly than exact isolated pitches.

Octave equivalency is when two notes an octave apart sound so similar that they're treated as basically the same note just in different registers.

Building the Major Scale

An octave happens when you have two notes whose frequencies form a ratio of 1:2.

Octave equivalency means only seven distinct notes are needed for the major scale which can then be translated up or down in octaves to fill out the rest.

A spectrum of functions from stable to unstable can be created by arranging six notes picked from a root going up five perfect fifths.

Understanding the Major Scale

In this section, we learn about the major scale and how it is constructed.

The Perfect 5th

Notes on the ends of our chain of 5ths are going to feel less stable than notes that have perfect 5ths on both sides.

Our perfect 5ths aren't actually 2:3 ratios anymore. Instead, we use a slightly smaller perfect 5th with a ratio of 1:2^(7/12).

Constructing Scales

Scales subdivide the octave into evenly spaced sections. We use 12 sections because it approximates many important frequency ratios.

Adding six extra notes distributed as evenly as possible gives us something like a major scale.

Finding the root and third by looking for where the notes cluster together helps illustrate those consonant notes' relationships to their neighboring dissonances.

Explaining the Major Scale

To explain the major scale to an alien, we would drill down as far as possible into math and physics shared language. But to explain it to a child, all you need is a nearby piano.

Playing all white keys from C up to next C is C major but this approach isn't ideal since humans are good at noticing patterns that don't mean anything in music theory.

Learning Scales

In this section, the speaker discusses how scales are defined by their interval structures and explains how to learn them.

Identifying Intervals

The speaker suggests starting with identifying different intervals like the octave and perfect 5th.

This introduces the idea of counting the number of keys between different pitches, which can be used to introduce the stepwise structure of the major scale.

Learning Major Scale on Guitar

The speaker explains that it's easier to explain scales on guitar because shapes don't change.

Learn a scale shape with any root, slide your hand up or down the neck to play that same scale on pretty much any other root.

To play a major scale on guitar, place your left-hand middle finger on any fret except for the first one. Then place your pinky two frets up on that same string. Next, go up a string and in order go index finger, middle finger, pinky. Repeat this pattern again but start with an index finger instead of middle finger.

Understanding Intervals

In this section, the speaker explains what intervals are and how they measure how far apart two notes are.

Explaining Intervals

An interval is a measure of how far apart two notes are.

Singing different pairs of notes can help you get a sense of what different sized intervals are like.

Octaves and Major Scales

In this section, the speaker explains octaves and scales in Western music, with a focus on the major scale.

Octaves and Scales

Octaves are very large intervals.

A scale is a set of notes that includes a starting note and some extra different notes in between.

The most important scale in Western music is the major scale.

The explanation relies on being able to produce a pitch that you can hear.

Importance of Understanding Musical Assumptions

Stripping musical ideas down to their bare necessities reveals the assumptions we make about how music works.

It's worth trying to explain basic music concepts without assuming any prior knowledge.
