Which of the following is NOT included in the list of note types?

The correct answer is "D," which is not included in the list of note types because "Forte" refers to a dynamic marking in music, indicating to play loudly. In contrast, "Whole," "Quarter," and "Half" are specific names for different types of musical notes that indicate the length or duration of a sound in music. A whole note lasts for four beats, a half note lasts for two beats, and a quarter note lasts for one beat. These definitions are standard in musical notation and help musicians understand how long to hold each note during a performance, whereas "Forte" pertains to how loudly a piece should be played and does not correspond to a note's duration or type.
