Question about music notes- black x?

Question

I have a question about a symbol in my music. I have play the alto saxophone. I have a #G followed by an #F in the key signature, but in the front of the F is a black X. What does this mean?

Answer 1

An X preceding a note means it's a double-sharp. They're used frequently when a measure is filled to capacity with other notes, often found in classical and Flamenco music.

The X in front of the F note means it is a G note.

The double flat is shown as bb and used in the similar way as a double -sharp.

Sometimes, you will find Xs or bbs in a key signature, but rarely done.

Answer 2

Than X means "double sharp" in other words you need to alter the F by two half tones. That means a G. But why the author put that instead of write a simple G? Well that's a little music theory, in a scale you are not able to write two times the same note, every note need to be different, that's why, to reach the note you need with out repeating, you alter two times a note, writing that X symbol. Hope this explain your question. Good luck.

Answer 3

He's right. The x just means that instead of raising a note a half step, you're raising it two half steps (or a whole step:)

It sounds silly, like, well why wouldn't they just write another note?? :) It's used for music theory reasons, kind of like how you can spell the word "their" three different ways.

Answer 4

An F with an x in front means that it is a F double sharp.

Answer 5

double sharp, or one whole step above the note (f double sharp would be g natural)

Answer 6

yup
