Meredith’s fa­ther played the vi­o­lin, and his mo­ther sang in the church choir. By age 10, Isaac was tak­ing or­gan les­sons. By age 12, he was sing­ing al­to in the choir at the Oak Street Meth­od­ist Church in Nor­ris­town. At 13, he was con­vert­ed by the per­so­nal in­vi­ta­tion of his bro­ther. For a num­ber of years, he sang to pri­son­ers in the coun­ty jail each Sun­day morn­ing. In the sum­mer of 1891, while va­ca­tion­ing in Ocean Grove, New Jer­sey, a Dr. Mun­hall in­vit­ed him to sing in evan­gel­is­tic meet­ings. Short­ly ther­ea­fter, he en­tered evan­gel­ism him­self & be­gan writ­ing Gos­pel songs. In 1893, Mer­e­dith & Grant Tul­lar found­ed the Tul­lar-Mer­e­dith mu­sic pub­lish­ing house. Mer­e­dith him­self com­posed over 1,000 songs. Dur­ing World War I, he served in France with the Young Men Christ­ian’s As­so­ci­a­tion. Af­ter the war, in ad­di­tion to his mu­sic bu­si­ness, he served as mu­sic di­rect­or for (at var­i­ous times) the Bushw­ick Av­e­nue Meth­od­ist Church, Brook­lyn, New York; and the Ped­die Me­mor­i­al Bap­tist Church and Cen­ten­a­ry Meth­od­ist Church, New­ark, New Jer­sey.
