Today, a man on television described his experience of , a condition in which the senses become joined. He explained that, when certain types of music are played, he often sees patterns of colors.

The correct answer is synesthesia.

Explanation:

Synesthesia is a non-pathological variation of human perception. Synesthetic people automatically and involuntarily experience the activation of an additional sensory or cognitive pathway in response to specific stimuli. For example, they can see a color when they hear a musical note, or feel touch on their right cheek when they savor a food. These perceptions are idiosyncratic, that is, each person perceives colors / smells / sounds, etc. concrete and different. Although in some websites it is said that synesthesia is a mixture of senses, this is inaccurate: in synesthesia there is sensory specificity, that is, sounds are heard as sounds, the color in which these letters are written are perceived. correctly (= black) and synesthesia is an additional sensation (a sound is perceived correctly as it is, and also, a color).

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !
