A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.

There are four types of compounds, depending on how the constituent atoms are held together:

• molecules held together by covalent bonds 通过共价键结合在一起的分子
• ionic compounds held together by ionic bonds 通过离子键结合在一起的离子化合物
• intermetallic compounds held together by metallic bonds 通过金属键结合在一起的金属间化合物
• certain complexes held together by coordinate covalent bonds. 某些配合物通过配位共价键结合在一起。

In music, metre/meter refers to the regularly recurring patterns and accents such as bars and beats. Unlike rhythm, metric onsets are not necessarily sounded, but are nevertheless implied by the performer and expected by the listener.

In musical notation, a bar (or measure) is a segment of time corresponding to a specific number of beats in which each beat is represented by a particular note value and the boundaries of the bar are indicated by vertical bar lines. Dividing music into bars provides regular reference points to pinpoint locations within a musical composition. It also makes written music easier to follow, since each bar of staff symbols can be read and played as a batch.

Simple metre and compound metre are distinguished by the way the beats are subdivided. Simple metre (or simple time) is a metre in which each beat of the bar divides naturally into two (as opposed to three) equal parts. Compound metre (or compound time), is a metre in which each beat of the bar divides naturally into three equal parts. That is, each beat contains a triple pulse.
