At what fret does the note C# occur on the 5th string?

To determine at which fret the note C# appears on the 5th string (the A string) of the guitar, it's essential to understand the musical note sequence and the relationship between the frets and the notes they represent.

The 5th string of a guitar, when played open, is an A. Moving up the neck, each fret represents a half step (or semitone) increase in pitch. Therefore, when counting the frets starting from the open string:

1. The 1st fret on the 5th string gives us A# (or Bb)

2. The 2nd fret gives us B

3. The 3rd fret gives us C

4. The 4th fret gives us C#

Thus, the 4th fret on the 5th string produces the note C#. Recognizing the pattern of semitones along the fretboard is crucial for identifying notes, as each fret corresponds directly to a half step increase from the note of the open string. This understanding allows guitarists to navigate the fretboard more effectively and reinforces the importance of familiarizing oneself with the note names as they play.
