有关键盘/十二平均律
有关pitch
The notion of pitch is not strict and refers to a perceptual property that allows a listener to order a sound on a frequency- related scale.
Two notes with fundamental frequencies in a ratio equal to any power of two (e.g., half, twice, or four times) are perceived as very similar. Because of that, all notes with this kind of relation can be grouped under the same pitch class. This observation also leads to the fundamental notion of an octave, which is defined to be the interval between one musical note and another with half or double its fundamental frequency.

还有一张精确到小数点后2位的，可惜太糊了：
有关chroma
In the music context, the term “chroma” closely relates to the twelve different pitch classes. For example, the notes C2 and C5 both have the same chroma value C. In other words, all notes that have the same chroma value belong to the same pitch class.

measure and beat
“小节“ -> measure；“节拍” -> beat
Music is typically organized into temporal units, referred to as beats. A measure (or bar) is a segment of time defined by a given number of beats.
Tempo
For example, the overall tempo and style of the piece may be specified by textual notations such as Allegro con brio (fast with vigor and spirit) or Andante con moto (moderate tempo with motion).
