E sharp

Yes, an E# is the same as an F natural. Sorry if this sounds obvious, but: a sharp raises the pitch 1/2 step, and a flat lowers it 1/2 step. Any note can be sharped or flatted. E# = F natural (pretty much).

So why would one write it as an E#? For example, in the scale of C# Mixolydian, the scale is properly written with an E# and F#. For this reason, the “F” note is known as E#. The same is true in F# Major and F# Harmonic Minor, which both have a major 7th scale degree, known as E#. You can read more about it here.

If you raise E by a half step, you have F. If you lower F by a half step, you have E. E# and F are called “enharmonic” - they sound the same note. But if you look at F and G on a keyboard, you'll see that there is a note between them.

The C♯ major chord is a triad formed from a root (C♯), a major third (E♯) and a perfect fifth (G♯).

You see this is the e chord. Maybe you know this already. Now if we want to sharpen the E chord. We'll do this with all the notes. So the e chord. We sharpen the e.

It exists but probably isn't included as an article because, whereas a scale like Db minor is a flat note with no "simpler" spelling*, E# is enharmonic to F which is a white key and arguably simpler / more common to read. Db minor also has double accidentals.

Just. So you know but let's have a look at it in theory. You see this is the e chord. Maybe you know this already. Now if we want to sharpen the E chord. We'll do this with all the notes.

And g-flat how is this useful. And harmonics can be useful when we are trying to see patterns in music take a look at. This. If we only call this note g flat a d major pentascale looks pretty strange.

Acoustically, they are exactly the same. In terms of music theory, a note would be called either D# or Eb depending on what key it appears in. Western music is divided into groups of sharp keys and flat keys. C major is neither a sharp key nor a flat key.

The a and the C right. So this is in fact an e sharp chord. Now because the e sharp chord is also a triad it has three notes right it also had what's known as three inversions.

The E♯ minor triad consists of the notes E♯, G♯ and B♯. The 2 inversions to the E♯ minor triad are G♯ B♯ E♯ and B♯ E♯ G♯. The E♯ minor 7th chord, abbreviated as E♯m7 or E♯min7, has the notes E♯, G♯, B♯ and D♯. The 3 inversions to the E♯ minor 7th chord are G♯ B♯ D♯ E♯, B♯ D♯ E♯ G♯ and D♯ E♯ G♯ B♯.

E# is the white key directly to the left of the group of three black keys. This is also called the F key. The white key directly to F's left is the E.
