新纪元音乐(New Age，又译作新世纪音乐)是一种在1970年代后期出现的一种音乐形式，原本与新世纪运动的信仰紧密相连，因此它包含的内容常与神秘事物相关（用途在于帮助冥思及作心灵的洁浄）。今日，它已经更多地与通常意义上的放松相提并论并被听者少量地接受，虽然其神秘的气息常通过音乐产品的包装和现场表演表现出来。具体来说，神秘主义代表了21世纪新世纪运动的特征。乐器的使用（包括传统的弦乐器）也为突出神秘的风格。为国人所熟知的Enya和Secret Garden等皆被归入此风格中。
At its beginnings, new age music was closely related to the New Age movement of beliefs, therefore, its contents have been constantly associated with mystical matters clearly present within the cultural movement. Today, it has become associated more with general relaxation and is taken lightly by most listeners, although a strong mystical perspective is often presented through the packaging of the music and the venues of purchase. To be specific, the mysticism present is characteristic of the 21st Century New Age movement.
“it draws freely from religious traditions around the world with very little deference to the clarity of the traditions' histories. This also can be applied to the music structures, instruments, and timbres. Often composers will utilize traditional instruments (or synthesized versions of them) with little relation to the musical context of their origin. For many critics, ethnomusicologists, and the like, this is the major criticism of this musical style: its vapid and potentially hegemenous appropriation of musical material and instruments.
