Musicians sometimes joke that the only mathematical knowledge they need is to count to 4. However, in the case of Anton Bruckner (born September 4, 1824), he could and did often count to 8. Many of Bruckner’s manuscripts, from sketches to full scores, contain his “metrical numbers,” which show he thought of his compositions as being built up of 8-measure phrases. In part because of these “metrical numbers,” musicologists can reconstruct Bruckner’s incomplete Ninth Symphony with greater certainty than is possible with the famous unfinished Tenths of Beethoven and Mahler.
