A# Major Piano Chord

Piano Diagram of A# Major in Root Position

To get an A# Major chord, you combine the root (A#), the 3rd (C_x which is called “C double sharp” and is an enharmonic equivalent of D), and the 5th note (E#) from the A# major diatonic scale. In other words, an A# Major chord is a major triad built upon the key of A#. Keep reading to get a better grip on the music theory behind this chord.

Music Theory and Harmony of A# Major

 

What are Major Chords?

Major chords are one of the two primary types of chords in music, along with minor chords. The primary distinction between the two lies in the 3rd note of the chord – major chords use a major 3rd, while minor chords use a minor 3rd. Due to the major third interval, major chords generally evoke a “happy” or “bright” quality, creating a sense of stability and resolution.

Building the A# Major Chord: Different Approaches

 

Starting from the A# Major Scale

To build a major chord, you can use the major scale as a reference. You will need to combine a root, a major 3rd, and a 5th interval.

For instance, to build the A# Major chord, you can start with the A# Major scale.

 

 

 

To create an A# Major chord, apply the formula R, 3, 5 in the following manner:

1. Begin with the root note, which is A#.
2. Select the major 3rd interval, which is C_x (D), and add it to the chord.
3. Finally, add the 5th interval, which is E# (F).

By following this simple formula, you can create a major chord from any major scale.

by Combining Intervals

One method to create a major chord is by combining specific intervals – a major 3rd, and a minor 3rd. For example, let’s consider the A# Major chord.

3 + m3 = Major Chords

By examining the intervals between the notes, we can see that A#-C_x (Bb-D) forms a major 3rd interval, and C_x-E# (D-F) creates a minor 3rd interval. These two intervals can be stacked together to create the A# Major chord.

A# Major in a Chord Progression

 

The following tables display the harmonization of major and their relative natural minor scales for keys that contain an A# Major chord in different positions (degrees of the scale).

A# major is a theoretical key with 10 sharps, including three double sharps and four single sharps, making it impractical due to the high number of accidentals. Musicians commonly opt for its enharmonic equivalent, Bb major, which has only two flats. This applies to other keys where an A# major chord is present, such as E# and D# major, as well as all minor keys (F_x, C_x, and B#). Therefore, it is more practical to refer to the equivalent chord, Bb major.

on Major Scales

on Natural minor Scales

• Mediant chord in G minor as Bb Major
