Oakland Choral Society

Our mission is to provide educational enrichment for Oakland County and metropolitan Detroit communities; to expand and enhance cultural experiences through dedication to the highest musical performance standards by presentation of significant classical and contemporary choral works; and to expose the listener to the finest choral literature in order to foster an appreciation of composers and singing. Our activities and performances are made possible through the generosity of individuals, local businesses, ticket sales, and chorus membership dues. We always welcome new supporters of music. OCS is 501(c) 3 nonprofit organization, and all donations are tax-deductible.

The artistic objectives we strive to achieve include interpretation of the compositions as the composer intended, with attention to dynamics, tempo, and to the emotions conveyed through the music. We aspire to perform each work with the original instrumentation dictated by the composer. Each concert, from preparation through performance, becomes another opportunity to improve our musicianship, our knowledge of the choral repertoire, and to present to our audience a concert that will keep them engaged so they will return for future OCS concerts.

Related to the artistic objectives are other considerations to enhance the experience of the audience and participants. These include choosing a performance venue that will "bring the music to life" with its ambiance and acoustics; selecting soloists who will complement the chorus, orchestra, and venue; providing a program booklet for the concert that will educate the participants about the works performed; and putting all of the above together to create a positive environment for the enjoyment of the concert.

Oasis Chorale

p>Like all high callings, thoughtful worship requires focus and effort. Certainly the call to worship is not exclusive to music, but permeates all areas of life. In the context of church music, however, the call to worship calls participants to give careful attention to both words and music. This can be learned and must be taught, and Oasis is committed to this process.

Worship cannot be divorced from a heart tuned to God. Oasis seeks participants eager for fully-orbed spiritual development.

Not all artistic music is rapidly attainable for all singers or accessible to all audiences. Artistic music usually requires training to be sung excellently and to be listened to with understanding and appreciation. Oasis intends to provide the necessary training to move singers and audiences forward one step in this process.

Ojai Community Chorus has been a vital part of Ojai since it was founded in 1987. It is a true community chorus: open to any singer of any age (professional or amateur, whether able to read music or not) who is willing to commit to the group's mission and put in the necessary work to achieve it. And that mission is to produce two shows a year (a themed performance in the spring and a holiday program in December) of the highest possible quality. Originally confined to religious/classical works, the chorus now performs a wide variety of music, both sacred and secular. A perfect example was our much-lauded Spring 2019 program, which featured a cornucopia of music from the jazz canon.

The chorus is extremely fortunate to be led by Connie Woodson, who has been our music director for the last 15 years.
