User interface techniques provide user vocalists with mechanisms for forward and backward traversal of audiovisual content, including pitch cues, waveform- or envelope-type performance timelines, lyrics and/or other temporally-synchronized content at record-time, during edits, and/or in playback. Recapture of selected performance portions, coordination of group parts, and overdubbing may all be facilitated. Direct scrolling to arbitrary points in the performance timeline, lyrics, pitch cues and other temporally-synchronized content allows user to conveniently move through a capture or audiovisual edit session. In some cases, a user vocalist may be guided through the performance timeline, lyrics, pitch cues and other temporally-synchronized content in correspondence with group part information such as in a guided short-form capture for a duet. A scrubber allows user vocalists to conveniently move forward and backward through the temporally-synchronized content.
