What are all the notes used in German musical notation?

In German musical notation, the notes are represented by the letters A, B, C, D, E, F, and G. Notably, the note B is referred to as "H" in German, while the note B natural is indicated as "B." The system uses these letters to denote pitches within the musical scale, and the octave is often indicated with additional markings, such as numbers or additional ledger lines.
