Note De Signature Simplifiée

How to write a love letter

[Music] what our accidentals accidents are notes that the composer put there by accident no accidents are not notes that were put there by accident they are notes that are outside of the key signature if this circle represents the notes that are inside the key signature then this smaller circle over here would represent the notes that are accidentals they're not in the key signature but though there is an option so how to accidentals work accidentals are marked with these symbols a flat sign means play the note a half step lower a sharp sign means play down a half step higher a natural sign means play the note without any sharps or flats accidentals are only played when marked and that only lasts until the end of the bar in this example the first note of the B flat and the second notice would be natural because of the accidental marking on it that only lasts until the end of the bar so in the next bar any B's that are written unless otherwise marked will be B flat because that is the note in the key signature accidentals are like the sriracha of music composers can use them to add a different flavor by using notes outside of the key signature flats sharps and Naturals are the most common accidentals but there are less common accidentals like double sharps and double flats a double sharp raises a note in the key signature by two half-steps and a double flat lowers the note in a key signature by two half steps and there are even more rare accidentals like half sharps and half flats which get into things like quarter tones which we won't get into today just know they're out there okay let's review a flat will tell you to play a note one half step lower than what is in the key signature in this example there are no sharps or flats in the key signature so if we see a B with a flat sign we would lower the B natural looking flat a sharp sign will tell you to play a note one half step higher than what is written in the key signature in this example there are no sharps or flats in the key signature so if we see an f-sharp we will raise the X next sharp and a natural sign will tell you to play a note without any sharps or flats in this example we already have a key signature with F sharp and C sharp in it so if we see an S natural we would play an F without the sharp thanks for watching let me know what you think in the comments below and I'll see you next time
