I can tell you, dearest friend, that if it became known how much friendship, love and a world of human and spiritual references I have smuggled into these three movements, the adherents of programme music - should there be any left - would go mad with joy.

In this quote, Alban Berg reflects on the depth of friendship, love, and spiritual references embedded within his music, particularly in the context of his compositions. He expresses that if the emotional and personal significance he has woven into his work were made public, it would delight those who appreciate programme music—a genre of music that aims to tell a story or convey specific emotions. Berg hints at the intimate connection between his personal life and the music he creates, making it clear that these elements are foundational to his art.

Berg's comment suggests that programme music—which often uses music to represent or evoke specific ideas or stories—can be more than just technical or structural. For him, the inclusion of human and spiritual aspects within the music elevates it beyond mere composition, turning it into something deeply personal and meaningful. His use of these references is a way of making his compositions not just works of sound but also expressions of his inner world.

The origin of this sentiment likely arises from Berg’s own life and experiences, particularly his deep involvement with the Second Viennese School, a group of composers who sought to push the boundaries of traditional music. As an artist, Berg was known for infusing his works with both personal and spiritual significance, often drawing on his own emotions and relationships to inform his compositions.

Ultimately, Berg’s quote underscores the idea that music is not merely a technical craft but a vessel for emotional expression, where the interpersonal and spiritual dimensions of the composer’s life are intricately woven into the work. His remark suggests that the true richness of his music would be fully appreciated by those who understand its deeper emotional layers.
