rhythm

Compared meaning: a repeated rhythm or pulse in music (noun).

比较义项：节奏、拍子（名词）。

• beat

  A single countable pulse or unit of musical time, used in phrases like 'four beats a bar'; not used for a general pattern of activity outside music or dance.

  指音乐中可数的单一拍子或计时单位，常用于“每小节四拍”这类说法；不用于音乐、舞蹈之外表示一般活动节奏的场合。

  This song has four beats in every bar, so it's easy to count.

  这首歌每小节有四拍，所以很容易数拍子。

• rhythm 本词

  The overall repeated pattern of sounds or movements, usually an uncountable noun; often extended metaphorically to the pace or flow of an activity outside music.

  指声音或动作反复出现的整体模式，通常是不可数名词；还常被引申用来表示音乐、舞蹈之外某项活动的节奏或步调。

  It took him weeks to find his rhythm as a new manager.

  他花了好几周才找到自己作为新任经理的节奏。

Beat and rhythm both mean a repeated pattern in music. Beat is one countable pulse, as in 'four beats a bar'. Rhythm is the whole pattern, usually uncountable, and can mean the pace of an activity. Beat can also mean to defeat someone; not compared.

beat 和 rhythm 都可以表示音乐或动作中反复出现的节奏，但 beat 强调稳定重复的单一拍子，常作可数名词；rhythm 强调整体的节奏模式，通常不可数，还可比喻活动的步调。这里不比较 beat 表示“击败”的动词义（如例句“我们队在决赛中击败了对手”）。
