2nd favourite第二最愛chord

The term "2nd favorite chord" is a bit ambiguous because it could refer to the second most commonly used chord in a specific genre, the second most popular chord in music theory, or even the second chord in a particular progression. However, I'll assume you're referring to the second most popular chord in music theory.

In music theory, the second most popular chord is likely the D minor chord (Dm). The reason for this is that it is the ii chord in the key of C major (C, Dm, Em, F, G, Am, Bdim). The D minor chord is also used extensively in many different genres, including pop, rock, jazz, and classical music.

However, it's important to note that the popularity of a chord can vary greatly depending on the genre of music. For example, in blues music, the dominant seventh chord (e.g., G7) is very popular, while in jazz, more complex chords like the minor seventh (Dm7), major seventh (Dmaj7), and suspended chords (Dsus4) are common.

Ultimately, the "2nd favorite chord" is subjective and can depend on personal preference, the style of music, and the context in which the chord is used.
