Accidentals in Music Theory: Part 2
Hey! I am Mark Black and I am here on expertvillage.com. I am here to talk to you about music theory and learning how to read music. We used a sharp, we can sharp a B, have a B sharp because it is just mathematical. Sharp raises one. Now the flat lowers one half step and we take our G and we lower it, this is the G flat, went down, on the piano that is one key, if that was a guitar it would move down one fret. Depending on the instrument that you have there are different ways to make that but in terms of theory and mechanically it moves down one half step. So here we have a B and we flat it, B flat. Here is the sound of B flat. And lastly the natural, and this little symbol which I have never seen anywhere except in music, the natural what it actually does it takes the note to the key of C where it’s neither sharp nor flat, but what most people look at it as is a symbol that neutralizes a sharp or a flat. So I had my G as a G flat and then I wanted to go back to G so I write the natural and now I undid my flat. So here is a G flat and I make it a G natural, remember the flat had lowered it a half step, the natural does not raise it half step it just takes away the flat. So we got rid of our lowered half step, we brought it back up to where it was and let us do the same thing for our D sharp so we have a D sharp and we say “let us make it a D natural,” let us move this back up a little bit more D sharp and D natural erases the sharp, takes it back to the key of C where the D is natural. Like that, okay. So there are two others, but this is the primary one, the natural essentially erases or eradicates the sharp or flat. So we can raise a note, you can lower a note and in fact like here is our F, I can write a natural on a note that is already natural just because I’m trying to remind everybody “hey! that’s the natural” did not do anything. So the natural takes the note to the key of C, typically is undoing a sharp or flat.
