AP Music Theory: Ultimate Modes Review 🎶

Hey there, future music maestro! Let's dive into the world of musical modes. This is your go-to guide for acing those questions on the AP Music Theory exam. We'll break down everything you need to know, from the classic modes to some cool extras. Let's get started!

Introduction to Musical Modes

What are Musical Modes?

Instead of just major and minor, modes give us a whole spectrum of sounds! Think of them as different flavors of scales, each with its own unique character. They're all about the specific pattern of whole (W) and half (H) steps.

• Modal music: Music based on a specific mode rather than a major or minor key. This creates unique melodies, harmonies, and chord progressions.

The Seven Traditional Modes

These are the core modes you need to know. Let's break them down:

1. Ionian: The major scale (W-W-H-W-W-W-H). Bright and happy. ☀️
2. Dorian: Like natural minor but with a raised 6th (W-H-W-W-W-H-W). Minor with a hint of major. 😌
3. Phrygian: Like natural minor but with a lowered 2nd (H-W-W-W-H-W-W). Spanish/Middle Eastern vibe. 💃
4. Lydian: Like major but with a raised 4th (W-W-W-H-W-W-H). Bright and dreamy. ✨
5. Mixolydian: Like major but with a lowered 7th (W-W-H-W-W-H-W). Dominant, bluesy feel. 🎸
6. Aeolian: The natural minor scale (W-H-W-W-H-W-W). Sad and serious. 🌧️
7. Locrian: Lowered 2nd and 5th (H-W-W-H-W-W-W). Tense and dissonant. 😬

How to Build Modes

Modes are built by starting on different degrees of a major scale:

• Dorian: Starts on the 2nd degree (supertonic).
• Phrygian: Starts on the 3rd degree (mediant).
• Lydian: Starts on the 4th degree (subdominant).
• Mixolydian: Starts on the 5th degree (dominant).
• Aeolian: Starts on the 6th degree (submediant).
• Locrian: Starts on the 7th degree (leading tone).

Relative Modes

• Ionian and Aeolian are relative keys (major and natural minor).
• Dorian and Mixolydian are also related. They often complement each other, especially when there's a dominant tonality.

Modal Music in Practice

• Gregorian Chants often use Dorian, Phrygian, Lydian, and Mixolydian modes. Listen here to get a feel for their sound.
• Modes are used in many genres, including jazz, folk, and pop.

History of Western Musical Modes

Ancient Greece

• Early modes had distinct characters and emotional associations.
• Seven modes: Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Ionian, and Locrian.

Middle Ages

• Church modes: Used in Christian music to reflect religious texts.
• Eight church modes: Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Ionian, Hypodorian, and Hypophrygian.

Renaissance

• Composers experimented with modes, leading to the development of tonality.
• Tonality based on major and minor keys.

Baroque Period

• Composers like Bach and Handel used modes while incorporating tonality.
• More complex modal system.

Classical Period

• Further development of modality by Mozart and Beethoven.

Romantic Period

• Modes fell out of favor, with major and minor keys becoming the norm.

20th Century

• Composers like Schoenberg and Stravinsky revived interest in modal composition.

Modern Usage

• Modes are still studied and used in classical music, jazz, and popular music.

Other Musical Modes

Pentatonic Scales

• Five-note scales used worldwide. 🌍
• Common in Asian music, blues, jazz, and rock.

Types of Pentatonic Scales

• Minor Pentatonic: 1st, 3rd, 4th, 5th, and 7th degrees of a natural minor scale (e.g., A minor: A C D E G).
• Major Pentatonic: 1st, 2nd, 3rd, 5th, and 6th degrees of a major scale (e.g., C major: C D E G A).

Blues Scale

• Variation of the pentatonic scale with a “blue note”.
• Root, minor third, fourth, fifth, and minor seventh, plus a flattened/bent fifth.
• Gives a bluesy, soulful sound. 🎶

Indian Ragas

• Similar to Western modes, with specific melodic rules.
• Each raga has a unique set of notes and guidelines for melody.
• Examples: Bhairav, Malkauns.

Other Scales

• Whole Tone Scale: All whole steps. 🎵
• Octatonic Scale: Alternating whole and half steps. 🎼
• Hexatonic Scale: Six-note scale. 🎶

• Free Response: Composing melodies in specific modes and analyzing modal pieces.

Last-Minute Tips

• Time Management: Quickly identify the mode or scale in question and move on if you get stuck.
• Common Pitfalls: Don't confuse modes with tonicization. Pay attention to the specific degrees that are raised or lowered.
• Strategies: Practice building scales and modes on paper. Listen to examples to internalize the sounds.
