In music theory, the terms major 7th, dominant 7th, minor 7th, and diminished 7th refer to different types of seventh chords. Here’s a brief explanation of each: 1. Major 7th chord: This chord consists of a root note, a major third, a perfect fifth, and a major seventh. For example, in the key of C major, a Cmaj7 chord would include the notes C-E-G-B. 2. Dominant 7th chord: This chord has a root note, a major third, a perfect fifth, and a minor seventh. In the key of C major, a C7 chord would co

A diminished 7th chord ("dim7" or "°7") is known for its tense sound. They sound great as passing chords, creating tension. E.G. C Maj7 - C#Dim7 - Dm7 - EbDim7 - Em7 To construct a diminished 7th chord, you start with a root note and stack minor thirds on top of it. Begin with the root note, a minor third, a diminished fifth, and a diminished seventh. A diminished 7th is a double flattened 7th (7bb) which is enharmonically equal to a major 6th Since the interval between each note is a minor thir
