Type 1 audiation refers to:

Type 1 audiation is characterized by the ability to hear music in one’s mind and understand musical concepts without the physical sound being present. This form of audiation primarily involves listening to music, whether it’s familiar or unfamiliar, and internally processing its structure, melody, harmony, and rhythm. This cognitive skill is foundational for a musician as it enhances their ability to comprehend and appreciate music, facilitating a deeper connection to the material being worked with, whether for analysis or performance.

This ability to audiate while listening allows musicians to anticipate musical events and understand the progression of musical ideas, even in pieces they have never heard before. It helps to deepen their musical knowledge and allows them to engage more fully with the music they study or perform.

The other options involve physical actions or different processes. Performing music from memory emphasizes recall and physical expression rather than the internal processing aspects of audiation. Inventing music using advanced techniques focuses on the creative aspect of music-making rather than purely understanding it through listening. Transcribing music by ear, while it does involve listening skills, is more about translating what one hears into notation, which is a distinct process from the internal understanding signified by Type 1 audiation.
