diminuído

Diminuído is a musical term in Portuguese, particularly used in Brazil and Portugal. It refers to a note or pitch class that has been lowered in frequency, creating a lower pitch. This concept is essential in Western tonal music, where the use of intervals and chord progressions is crucial.

In a harmonic context, diminuído is the Portuguese term for the lowered form of a chord, known as a minor chord. When a major chord is transformed into a minor chord, the frequencies of the notes within that chord are lowered. For example, a C major chord (C-E-G) becomes a C minor chord when the E is lowered to Eb (C-Db-G), or when the G is lowered to Gb (C-Eb-Gb).

The term diminuído is also used in music theory to describe a specific alteration to a pitch or a chord. When a note is lowered, it indicates a change in the chord's or scale's identity. In contrast, an augmented scale or chord would raise a note above its original pitch class.

The use of diminuído is particularly relevant in traditional music from Brazil and Portugal, as well as other genres that draw on these musical traditions. By understanding and mastering the concept of diminuído, musicians can better navigate chord progressions and melodic structures to create a range of tonal colors and expressiveness.
