Quartet 2

Quartet 2 gives little away about what a person actually does with it: the music category could cover listening, making music, learning, or instrument practice. That makes it difficult to compare with a specific kind of music app or judge what its main strength might be. By our assessment, the name and category support only a cautious, middle-ground view rather than a claim about particular tools. The useful distinction would be whether it plays music, helps create it, or teaches it.
