Why is there an A natural in E major key

Why is there an A natural in E major key?

The presence of an A natural in the key of E major can be attributed to several factors, including cautionary accidentals, modulations and key changes, and the relationship between E major and its relative minor key, C♯ minor.

Cautionary Accidentals

In musical compositions, cautionary accidentals are used by composers or editors to clarify the intended pitch, even if it is not necessary according to the key signature. These accidentals are employed to avoid confusion for the performer. In the case of the E major key, the inclusion of an A natural may be a result of a preceding A sharp, which is not part of the key signature. The A natural serves as a cautionary accidental to ensure that the performer interprets the correct pitch.

Modulations and Key Changes

Music written in a particular key may undergo modulations or temporary shifts to different keys. During these modulations, accidentals are often used to indicate the change in tonality. In the context of E major, there may be sections in a composition where the music temporarily shifts to a different key, such as E minor or another related key. These modulations can involve the use of accidentals, including A natural, to establish the new tonal center and create harmonic interest.

Harmonic and Melodic Minor Scales

The key of E major has a relative minor key, which is C♯ minor. In the harmonic and melodic minor scales of C♯ minor, the seventh note (B) is raised by a half step to B♯. This alteration affects the harmony and melody, potentially leading to the use of A natural in certain passages. The A natural serves as a chromatic note that adds color and tension to the music, creating a distinct emotional effect.

Overall, the presence of an A natural in the E major key can be attributed to cautionary accidentals, modulations and key changes, and the relationship between E major and its relative minor key, C♯ minor. These factors contribute to the rich and varied tonal palette available to composers and musicians in the exploration of E major and its related tonalities.
