The role of music theory in the composing process
Introduction to music theory
Music theory is the study of the language and structure of music. It involves analyzing and understanding the various elements that make up a piece of music, such as melody, harmony, and rhythm. Knowledge of music theory can be extremely useful for composers, as it provides a set of tools and guidelines for creating music that is well-structured, coherent, and aesthetically pleasing.
For more information see The Role of Scales and Modes on Music Composition and Music Making.
Scales and modes
A scale is a series of pitches arranged in a specific order, typically based on the intervals between the pitches. There are many different scales in Western music, including major, minor, and modes such as Dorian and Phrygian. Composers can use scales to create melodies and harmonies that are consonant (pleasing to the ear) or dissonant (clashing or unstable). Knowledge of scales and modes can help a composer choose the right pitches to create the desired mood or emotion in a piece of music.

Chords
A chord is a group of three or more pitches played simultaneously. Chords can be formed by combining any combination of pitches, but some chords are considered more harmonically stable than others. Major and minor chords, for example, are often used to create a sense of tonality (a feeling of being "in" a particular key). Composers can use chords to add depth and complexity to a piece of music by layering different harmonies on top of each other.

Harmony
Harmony refers to the way that chords and melodies work together in a piece of music. In tonal music (music that has a clear sense of being in a particular key), the melody often follows the chord progression, with the chords supporting and reinforcing the melody. Composers can use harmony to create a sense of tension and release, or to create a sense of movement and progression within a piece of music.
We have more discussion on The Role of Harmony in Composition.
Form
Form refers to the overall structure of a piece of music. It determines how the different sections of a piece fit together and how the piece develops over time. There are many different forms that composers can use, such as verse-chorus form (a repeating section followed by a contrasting section) or sonata form (a three-part structure consisting of an exposition, a development, and a recapitulation). Knowledge of different forms can help a composer create a piece of music with a clear sense of direction and purpose.
Melody
Melody is the most prominent and memorable part of a piece of music. It is the tune that stays in our head after we hear a song. Composers can use melody to create a sense of emotion or to convey a particular message. Knowledge of melody writing can help a composer create a memorable and effective melody that engages the listener.
We have a discussion of the role of Melody in music making.
Rhythm
Rhythm refers to the way that time is divided and organized in a piece of music. It can be created through the use of beats, tempo (the speed of the music), and meter (the grouping of beats into larger units). Composers can use rhythm to create a sense of momentum, to add excitement to a piece of music, or to create a sense of calm and relaxation.

Conclusion
In conclusion, music theory plays a crucial role in the composing process by providing composers with a set of tools and guidelines for creating well-structured, coherent, and aesthetically pleasing music. Knowledge of scales, chords, harmony, form, melody, and rhythm can all influence a composer's decisions and help them create music that speaks to the listener on a deep emotional level.
