Designed for major universities, conservatories, music schools, and large library systems, Tier Four provides one-year institutional access for more than 120 users and until 400.

Students, faculty, singers, pianists, guitarists, collaborative musicians, and researchers can access the complete MundoArts Digital Library through a secure online environment designed for large-scale academic use, performance preparation, teaching, language study, and research.

The platform supports campus-wide and remote access through secure login, IP-based authentication, and SSO integration, allowing seamless use across computer and tablet devices without downloads.

Tier Four is ideal for institutions with extensive academic communities and multiple departments seeking comprehensive access to specialized Latin American and Iberian vocal repertoire, integrated pedagogical resources, and continuously expanding collections not available in standard databases.
