On January 10, Betty, of Emanon, Missouri, visited the showrooms of the Forte Piano Company in St. Louis and selected a piano. A sales memorandum of the transaction signed both by Betty and by the salesman of the Forte Piano Company read as follows: ‘‘Sold to Betty one new Andover piano, factory number 46832, price $3,300, to be shipped to the buyer at Emanon, Missouri, freight prepaid, before February 1.

Prior to shipment, seller will stain the case a darker color in accordance with buyer's directions and will make the tone more brilliant.'' On January 15, Betty repudiated the contract by letter to the Forte Piano Company.

The company subsequently stained the case, made the tone more brilliant, and offered to ship the piano to Betty on January 26. Betty persisted in her refusal to accept the piano. The Forte Piano Company sued Betty to recover the contract price. To what remedy, if any, is Forte entitled?
