“FaSoLaMix” is designed to teach Sacred Harp singing to newer singers. When someone wants to learn to sing, our instinct is usually to recommend that the inquirer go to a good singing and sit next to a strong singer. But not everyone lives near many all-day singings. Our intent is to give the listener the virtual experience of sitting next to a couple of strong singers in whichever section suits their voice. The app features high-quality recordings of many Sacred Harp songs where the mix of the four parts can be controlled manually. For example, a singer wanting to learn the treble line of a particular song could leave the treble track at full volume, mute the other three parts, and sing along with the solo treble part for practice. While the most obvious benefit will be to new singers, longtime singers will also find it useful and fun. For example, experienced singers may wish to mute one part and fill in that missing part with their own voice. This app comes bundled with recordings of 35 songs, ranging in difficulty, all of which are regularly called at all-day singings and conventions. More recordings will become available for sale periodically in the form of “song packs” which will generally include several songs. Songs included: 30t LOVE DIVINE 36b NINETY-FIFTH 56t COLUMBIANA 65 SWEET PROSPECT 68b ORTONVILLE 84 AMSTERDAM 87 SWEET CANAAN 89 THE CHURCH’S DESOLATION 99 GOSPEL TRUMPET 101t CANAAN'S LAND 112 THE LAST WORDS OF COPERNICUS 155 NORTHFIELD 176b BLOOMING YOUTH 178 AFRICA 182 NEWBURGH 192 SCHENECTADY 196 ALABAMA 198 GREEN STREET 200 EDOM 216 DELIGHT 276 BRIDGEWATER 277 ANTIOCH 282 I’M GOING HOME 318 PRESENT JOYS 349 A CROSS FOR ME 384 PANTING FOR HEAVEN 411 MORNING PRAYER 436 MORNING SUN 440 NORTH SALEM 448b THE GRIEVED SOUL 456 SACRED MOUNT 472 AKIN 480 REDEMPTION 542 I’LL SEEK HIS BLESSINGS 546 MY BRIGHTEST DAYS All songs from The Sacred Harp, 1991 “Denson” Revision, used by permission of its publisher, the Sacred Harp Publishing Company, Inc., Carrollton, GA. The developers of this app in no way personally profit from the sale of this app. All proceeds will be used to prepare more recordings for future updates with excess used to support the Sacred Harp Musical Heritage Association, a 501(c)(3) non-profit organization whose purpose is the preservation and perpetuation of Sacred Harp singing and its traditions.
