As a music theory expert with a deep understanding of the intricacies of the musical scale and its historical development, I can provide a comprehensive explanation for why there is no E♯ (E sharp) or B♯ (B sharp) in the standard Western musical notation system.
The Western musical system is based on the chromatic scale, which consists of 12 pitches. These pitches are arranged in a pattern of whole and half steps. A whole step is the distance between two adjacent notes on a piano keyboard, and a half step is the smallest interval between any two pitches. The pattern of whole and half steps in the chromatic scale is W-W-H-W-W-W-H, which repeats every octave. This pattern is essential for understanding why there are no E♯ or B♯ notes.
The chromatic scale is derived from the diatonic scale, which is the foundation of Western music. The diatonic scale consists of seven notes: A, B, C, D, E, F, and G. These notes are arranged in a specific pattern of whole and half steps, which is W-W-H-W-W-W-H. The diatonic scale is used to create major and minor scales, which are the basis for most Western music.
Now, let's delve into the specific reasons why there are no E♯ or B♯ notes in the chromatic scale:
1. Acoustical Constraints: Acoustically, the intervals between the notes of a scale are determined by the frequency ratios of the pitches. The most consonant intervals, such as the octave, fifth, and fourth, are based on simple frequency ratios. The half step is the smallest interval that maintains a sense of consonance while providing a clear distinction between adjacent pitches. There is no room for an additional pitch between E and F or B and C without disrupting the harmonic relationships that are fundamental to Western music.
2. Harmonic Function: In Western music, chords are built on specific scale degrees. The absence of E♯ and B♯ allows for the creation of chords that have specific harmonic functions, such as the major and minor chords. If E♯ or B♯ were to exist, it would alter the structure of these chords and the harmonic progressions that are characteristic of Western music.
3. Enharmonic Equivalence: The concept of enharmonic equivalence is crucial to understanding the absence of E♯ and B♯. Enharmonic notes are different notations for the same pitch. For example, F is enharmonically equivalent to E♯, and C is enharmonically equivalent to B♯. This means that while there are no separate E♯ or B♯ notes on the staff, the pitches they represent are still accessible through the use of enharmonic equivalents.
4. Historical Development: The development of the Western musical system has been influenced by various factors, including cultural, technological, and mathematical considerations. The absence of E♯ and B♯ can be traced back to the historical evolution of the system, which has been shaped by the need for a consistent and logical organization of pitches.
5. Simplicity and Clarity: The exclusion of E♯ and B♯ from the chromatic scale contributes to the simplicity and clarity of the system. By limiting the number of distinct pitches, musicians can more easily navigate the musical landscape and understand the relationships between different notes.
6. Notational Efficiency: From a notational standpoint, the absence of E♯ and B♯ allows for greater efficiency in writing and reading music. With fewer symbols to represent, there is less potential for confusion and a more streamlined appearance on the musical staff.
In conclusion, the absence of E♯ and B♯ in the Western musical notation system is a result of acoustical constraints, harmonic function, enharmonic equivalence, historical development, simplicity and clarity, and notational efficiency. These factors have shaped the system into what it is today, providing a rich and versatile framework for the creation and performance of music.

Simply because, acoustically speaking, there is no room in our current system for another pitch between B and C, or E and F. ... A sharp always refers to raising the pitch by a half step, and a flat always refers to lowering the pitch by a half step.
