A Chamber Music Exploratorium

chamber music exploratorium earsense is the chamber music exploratorium built on a comprehensive database of composers, works and related multi-media resources including audio, video, program notes, scores, wikipedia pages and other links. Presenters, performers and works are joined in a smart calendar of upcoming and past, archived events that capture the living performance history of chamber music. Everything is integrated and accessible through a sophisticated search interface as well a variety of featured links and relationships for spontaneous, exploratory browsing. Using the latest media of our time, earsense gives chamber music a first-class presence on the web with endless possibilities for expansion and enrichment.

With a specific, deep focus on chamber music, earsense avoids the typical web site problem of being overly general, superficial and sparse. The world of chamber music is sufficiently vast in itself; it deserves a dedicated resource that is deep as well as broad, focused rather than incomplete, poorly integrated and “noisy” and distracted.

The ubiquity and flexible accessibility of the web enables users to connect to earsense from a school, a library, an internet café, a home computer or a cell phone around the world, anytime, for free. For education, research or pure musical pleasure, earsense makes chamber music available in a supremely “democratic” way to anyone who has the desire to explore, research, discover and listen.

The earpage

The centerpiece of earsense is the earpage, a web page representing a single chamber music work. The earpage is a central reference for a specific work including all the information and media necessary to give that work a rich and respectful context. It provides essential reference data including composer, title, dates, ensemble, movements, duration, dedication, etc. as well as a dynamic set of relevant multi-media resources including program notes, audio and video, recordings, scores, wikipedia pages etc. Each earpage features a context-sensitive glossary of relevant musical terms and musical instrument profiles. Upcoming features will add a set of related earsense links such as other works by the composer, the composer’s contemporaries, countrymen, teachers, students, etc. The earpage provides actions for printing, formatting, copying, commenting, sharing and embedding. Ultimately, an earpage is a reference, a lesson, a virtual chamber music concert, a master class and a page within a living historical archive.

earsense Audience

earsense is useful for just about every member of the chamber music field, several of which are detailed below.

Composers & Publishers

earsense is designed to list composers, their chamber music works, images, dates and links to official web sites including publishers for obtaining scores. Composers can ensure their works will be included in earsense queries, features and a network of associations and relationships.

Performers & Managers

Performers can use earsense to discover new repertoire (with queries by ensemble, instrumentation, ratings etc.), to showcase a performance audio or video, to publish and maintain concert calendar events and provide a calling card with images, web site links etc. Upcoming features will enable performers and managers to list their repertoire and schedule to negotiate bookings with presenters.


Chamber music presenters and producers can publish and maintain calendar events linking performers and works to venues, dates and series including information about premiers, pre-concert talks and links to external web sites. earsense provides supporting information such as program listings with accurate technical information, program notes and pointers for additional research. Upcoming features will enable presenters to list their season, venues and schedule to negotiate bookings with managers and performers.

Students, Teachers, Writers & Speakers

earsense offers a comprehensive model of the chamber music repertoire including composers, works and sophisticated queries to relate them by date, period, nationality, tags or associations and other interesting relationships. Each earpage gathers pointers to additional resources for study. Audio and video resources enable a student to experience multiple interpretations, diverse technique, etc.

Music Lovers, Enthusiasts and Explorers

earsense was designed and implemented by and ultimately for the chamber music lover. Listening to works, discovering new composers, reading program notes and learning about the technical, historical and aesthetic context of the music is the essence of earsense. The home page offers daily features to “bubble-up” new material for discovery or repeated exploration. Upcoming enhancements will enable users to create “studylists” track concerts, and receive regular customized emails to maintain a “discipline” or a continuity of on-going musical experience.

Embedding Content—The Data Server

earsense is also a “data server” providing content for other sites. Members can “embed” data in their own web sites including composer and work information with dates, movement listings, audio, visual and other related media.

Inspirations, Case studies and "Mash-ups"

earsense benefits from a close study of a variety of technologies including Google, Amazon, Wikipedia, YouTube, Grove Music online, iTunes, the gracenote CDDB, IMSLP, and others. Their virtues and shortcomings have inspired the design and features of earsense. Ultimately, earsense is a blend, literally gathering resources from several of these technologies in vast collaborative “mash-up” integrating disparate media into a central, curated source. earsense is a chamber music portal.

Community Collaboration

The vast amount of information comprising earsense ultimately needs a community for its care. Upcoming features will enable users to add, edit and comment on earsense information much like the model provided by wikipedia and other collaborative sites. Users can add composers, works, tags, ratings and comments as well as provide links to multi-media resources such as external sites, audio and video, scores, program notes etc. Over time, a community will ensure that earsense pursues its ever-elusive goals of being comprehensive, reliable, rich, relevant and useful, a dynamic resource for the chamber music community.
