Why C Harmonic Major is Preferred
B-sharp harmonic major would theoretically require numerous sharps and double sharps, creating an unreadable notation system for what is simply the C harmonic major scale with no sharps or flats. C harmonic major uses entirely natural notes except for the lowered sixth degree (A-flat), making it one of the most accessible harmonic major scales to read, write, and perform. The notational simplicity of C harmonic major compared to its B-sharp enharmonic equivalent represents one of the most extreme cases of practical preference in music theory.
Practice Recommendations
There is no practical reason to ever use B-sharp harmonic major notation. Instead, study and practice C harmonic major, which provides the same pitches with straightforward notation. When learning harmonic major scales, C harmonic major is often recommended as a starting point due to its similarity to the C major scale, requiring only one altered note. Understanding this enharmonic relationship reinforces the importance of choosing appropriate enharmonic spellings based on context and readability.
