Modes are different from scales, although both are collections of pitches. A scale is a series of notes that are arranged in ascending order, while a mode is a collection of notes that have a specific intervallic relationship to each other. For example, the major scale is a seven-note scale that consists of two whole tones, two semitones, three whole tones, and a semitone. The Dorian mode is also a seven-note scale, but it consists of two whole tones, one semitone, two whole tones, one semitone, and one whole tone.
There are many different modes that can be used in music, and each one has its own unique sound and character. Some of the most common modes include the major mode, the minor mode, the Dorian mode, the Phrygian mode, and the Lydian mode.
Modes are used in a wide variety of musical genres, including classical music, folk music, and popular music. In classical music, modes are often used to create different types of moods and atmospheres. In folk music, modes are often used to express different cultural traditions. In popular music, modes are often used to add interest and variety to a song.
By understanding the different types of modes and how they can be used, you can create music that is more expressive and interesting.
