'x' on a piece of sheet music for piano? (picture included)?

learning (slowly) to play a new sonata on the piano. i've never seen this notation before - what does it mean?'x' on a piece of sheet music for piano? (picture included)?
The x in front of a note is a double sharp. It means to raise the note 2 half steps (1 whole step). An ';F double sharp'; would be a ';G';. A ';C double sharp'; is a ';D';.


It is necessary for ,and simplifies, the melodic and chordal writing in certain keys, especially those with many sharps.


There is also a double flat but it is more apparent since it is simply two flat signs placed in front of a note.





Hope this helps.

Bearcat is correct; it is a double-sharp, but many people want to know why a double-sharp is used. If you see an F double-sharp, why not just write a G natural? Well in the case of the music that you have provided, it is to avoid cluttering the music. You have a triplet pattern going from G# to F double-sharp back to G#. If you used G# to G natural to G#, an accidental would have to be written for every note. This makes more to read and can be a bigger hassle for the performer. In summary double-sharps are often used in chromatic passages simply to avoid clutter.





The other reason it is used is that it fits the key. For example, in G# minor, a V chord (a D# major chord) would be notated D#, F double-sharp, A#.





I hope this sheds some light on the subject.
