About

Opus

Features
Read full description

Opus is a classical listening companion for people who want to understand the music as it unfolds. Start from the player you already use. Opus works with Apple Music, Apple Music Classical, Spotify, and shared track links from other music apps, so a piece can become clearer whether you are listening live or returning to a recording you found elsewhere. As the music plays, Opus helps you move from the passage in front of you to the larger work around it: the composer, the structure, the form, and the world that shaped the music. Opus creates AI-assisted listening introductions that stay close to the music instead of interrupting it, so a symphony, sonata, concerto, or opera becomes easier to follow while you are still inside the experience. Choose the depth that suits the way you listen. Listener is free and offers a welcoming way in, with a clear sense of mood, character, and dramatic shape. Enthusiast opens a broader view of structure and musical context, helping you follow themes, contrasts, and the arc of the work. Connoisseur goes further into form, style, and interpretive detail for listeners who want a deeper reading of what they hear. Whether you are meeting a piece for the first time or returning to a familiar recording, Opus helps you listen with sharper ears and a stronger sense of the work as a whole.
