YOU learn about accidentals in level 2 in piano. Accidentals in piano are when there are flats or sharps next to a note that was not given in the key signature.
A natural sign cancels all applicable accidentals in that bar as well as accidentals in the key signature. However, in the case of the key signature accidentals, the natural sign is only applicable to that bar.
look for any accidenatls in the scale. If there are no accidentals, then it's a major scale, vise versa. All the sharps and flats should be included in the key signature of the scale.
The white notes E -> F and B -> C are a semitone apart. They do not require accidentals when present in any key in which those particular notes are not altered in the key signature, but do require accidentals if the corresponding notes in the key signature automatically raise or lower them by a semitone accordingly.
Sharps and Flats
When there are no flats or sharps in the key signature and or when there are no accidentals.
In the key of D major, the accidentals are F# and C#. The key signature consists of two sharps: F# and C#. These accidentals are essential for establishing the major tonality and contribute to the scale of D major, which consists of the notes D, E, F#, G, A, B, and C#.
b flat
In the key of C major, there are no accidentals; it consists solely of the white keys on a piano: C, D, E, F, G, A, and B. This scale is characterized by a natural sound without any sharps or flats. Therefore, all notes in the C major scale are in their natural form.
A natural sign cancels all applicable accidentals in that bar as well as accidentals in the key signature. However, in the case of the key signature accidentals, the natural sign is only applicable to that bar.
Johann Sebastian Bach 'discovered' the chromatic scale, and composed the Circle of Fifths. The Circle of Fifths starts with the key of C, which has no accidentals (flats or sharps). The fifth note of C is G, when means when you play or write these scales, you move from the key of C to the key of G - moving up a perfect fifth; hence, the term 'circle of fifths'. The key of G major has one accidental, the F sharp. The fifth note of the key of G is D, and the key of D major has TWO sharps - so you see, as you move through the circle of fifths each change increases the number of accidentals by one. For instance, the fifth note of D is A, and the key of A major has THREE accidentals. That is pretty much why the key of G major has an accidental, which in the case of that scale, happens to be F sharp.
Instead of writing a sharp in the key signature, write one next to the F when you write out the scale.

A key signature, accidentals, a piece of music.
Sharps and Flats
When there are no flats or sharps in the key signature and or when there are no accidentals.
Sometimes for melodic purposes, a composer will want to use a note that is not in the key signature. Accidentals are used to alert the performer that the note has been altered.
