What does a half note look like in music notation?

A half note in music notation is represented by a filled note head combined with a stem. The filled note head differentiates it from other note types, such as a quarter note, and the presence of the stem indicates the duration of the note. A half note typically lasts for two beats in common musical time signatures, making it essential for rhythmic representation in a piece of music. This notation helps musicians understand the value and timing of notes in a composition, ensuring clarity in performance and interpretation.
