Accelerando Music Service was established in 1989 by Harold and La Rue Lewallen of Odessa, Texas.
After 21 years of serving music customers in Texas and across the United States, the Lewallens sold
Accelerando in 2010 to Hart Music of Texas. Tonya Hartsfield, owner of Hart Music of Texas, was
joined by her husband Ross Hartsfield in the purchase of Accelerando Music Service.
