The C major key has been a popular choice for blues musicians for several reasons. Firstly, it is a natural key that resonates well with the human voice, making it ideal for singing and performing.

The C major scale also provides a harmonically rich palette for musicians to explore, with a variety of chords and scales that can be used to create a distinctive blues sound.
One of the key elements of C jam blues is the use of the blues scale, which is a minor pentatonic scale with the addition of the flattened fifth. This scale, also known as the “blues box,” consists of the notes C, D, E♭, F, G, A♭, and B♭. The flattened fifth, or “blue note,” adds a distinctive tension and release to the music, contributing to the bluesy feel of the genre. When playing in the key of C major, the blues scale can be used to create a soulful and expressive performance.
Another important aspect of C jam blues is the use of the 12-bar blues progression, which is a common chord progression in blues music. The progression typically follows a specific pattern of chords, with the first four bars being a I-IV-V-I (C-F-G-C) pattern, and the next eight bars consisting of a V-I-IV-I-I-V-I-I (G-C-F-C-C-G-C-F) pattern. This progression provides a clear structure for the melody and harmony, allowing musicians to focus on improvisation and expression.
