Here's how you play the note A Sharp on the bass guitar. So, if we know that our open string is A, which is the string that's second closest to us. And we call that String 3, because it goes from the top, 1, 2, 3. If we know that this is A, then by pressing down the first fret, we get A Sharp. If we press down the second fret, we get B. So what we know is that A Sharp is the note between A and B. All the notes that are between two different notes that just have a solid note name, always have two names. So, A Sharp is also called B Flat. So, if we have A Sharp and B Flat, on the first fret of our A string, it's also found on the sixth fret of the E string. And it's the same note. We can also find it an octave up by playing on the G String, on the very highest string on the third fret. And you can check it by going back to the one you already know. And that's going to be the same as the eighth fret on the D String. It's going to be same as the thirteenth fret on the A String. So, we can always find them by checking one we already know or a note we already know like A and then knowing that A Sharp is just mean we're going to raise it by one half step or one fret. And that's how you play the note A Sharp on the bass guitar.
