paragraphs, chapters, stanzas, scenes, or episodes, each with their own endings, to help us keep track of things and understand what is going on. Music also groups phrases and motifs into verses, choruses, sections, and movements, marked off by strong cadences to help us keep track of them. In good stories, there are clues in the plot and the pacing - in the Western tradition, the chase gets more exciting, characters good and bad get what they deserve, the inevitable tragedy occurs, or misunderstandings get resolved - that signal that the end of the story is nearing. Similarly, in music there are clues that signal to the listener that the end is coming up. These clues may be in the form; in the development of the musical ideas; in the music's tempo, texture, or rhythmic complexity; in the chord progression; even in the number and length of the phrases (Western listeners are fond of powers of two). Like the ending of a story, an ending in music is more satisfying if it follows certain customs that the listener expects to hear. If you have grown up listening to a particular musical tradition, you will automatically have these expectations for a piece of music, even if you are not aware of having them. And like the customs for storytelling, these expectations can be different in different musical traditions.

Some things that produce a feeling of cadence

Harmony - In most Western and Western-influenced music (including jazz and "world" musics), harmony is by far the most important signal of cadence. One of the most fundamental "rules" of the major-minor harmony system is that music ends on the tonic. A tonal piece of music will almost certainly end on the tonic chord, although individual phrases or sections may end on a different chord (the dominant is a popular choice). But a composer cannot just throw in a tonic chord and expect it to sound like an ending; the harmony must "lead up to" the ending and make it feel inevitable (just as a good story makes the ending feel inevitable, even if it's a surprise). So the term cadence, in tonal music, usually refers to the "ending" chord plus the short chord progression that led up to it. There are many different terms in use for the most common tonal cadences; you will find the most common terms below. Some (but not all) modal musics also use harmony to indicate cadence, but the cadences used can be quite different from those in tonal harmony.

Melody - In the major/minor tradition, the melody will normally end on some note of the tonic chord triad, and a melody ending on the tonic will give a stronger (more final-sounding) cadence than one ending on the third or fifth of the chord. In some modal musics, the melody plays the most important role in the cadence. Like a scale, each mode also has a home note, where the melody is expected to end. A mode often also has a formula that the melody usually uses to arrive at the ending note. For example, it may be typical of one mode to go to the final note from the note one whole tone below it; whereas in another mode the penultimate note may be a minor third above the final note. (Or a mode may have more than one possible melodic cadence, or its typical cadence may be more complex.)

Rhythm - Changes in the rhythm, a break or pause in the rhythm, a change in the tempo, or a slowing of or pause in the harmonic rhythm are also commonly found at a cadence.

Texture - Changes in the texture of the music also often accompany a cadence. For example, the music may momentarily switch from harmony to unison or from counterpoint to a simpler block-chord homophony.

Form - Since cadences mark off phrases and sections, form and cadence are very closely connected, and the overall architecture of a piece of music will often indicate where the next cadence is going to be - every eight measures for a certain type of dance, for example. (When you listen to a piece of music, you actually expect and listen for these regularly-spaced cadences, at least subconsciously. An accomplished composer may "tease" you by seeming to lead to a cadence in the expected
