# PaceResult A pace analysis results for the song. ``` struct PaceResult ``` ## Overview The results indicate the energy and momentum of the music over time. Parts of a song that feel faster or more energetic have a higher value compared to slower or less energetic parts of a song. These values represent a perceptual events-per-minute rate. The perceptual events-per-minute rate allows you to synchronize behaviors with the music’s changing energy, independent of the fixed tempo. For example, a song with a high BPM might yield a lower `Pace` value during a sparse breakdown. ## Topics ### Getting the range [`let ranges: [MusicUnderstandingSession.RangedValue]`](/documentation/MusicUnderstanding/PaceResult/ranges) The pace for a range of a song. ## Relationships ### Conforms To [`Sendable`](/documentation/Swift/Sendable) [`Encodable`](/documentation/Swift/Encodable) [`Decodable`](/documentation/Swift/Decodable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) --- Copyright © 2026 Apple Inc.
