let's look at our C major scale on the keyboard of a piano first notice that we only use the white keys let's begin on the middle C and play the eighth note scale in the treble clef to the next C ascending now let's begin on middle C and play the C major scale descending in the bass clef still using the piano keyboard let's study the black notes to do this we need to understand accidentals the two primary accidentals are a sharp and a flat these signs always precede the note the sharp changes the note in an upward direction while a flat changes the note in a downward direction let's play a G in the treble clef on the second line if we add a shot we have written the note G sharp and it is the black key on the piano keyboard just above the G if we place a flat in front of the G the note becomes a G flat and we play the black key just below the G let's also do this exercise on an a first the a now an a shot now the a again and then a flat you've probably noticed that the G sharp and the a flat are the same sounding note but of course they're notated differently this is called an and harmonic equivalent the notes have different names but they sound the same if we place a sharp in front of a C at a flat in front of a D these notes sound the same but again are spelled and harmonically on our piano keyboard noticed that between the B and C and the E and F there is no black key therefore a C flat is the same as it'd be natural and a B sharp is the same as a C natural and a flat is the same as an e natural and an e sharp is the same as an F natural
