The choice of music font can help put the musicians in the right frame of mind even before they've started playing. Petrucci's clean neutrality is great for choral music or anything involving a fairly dense layout. Sonata is subtly different; a bit bolder and fancier, it works especially well with piano music and small, "classical" ensembles. GoldenAge is totally cool -- it's perfect for jazz and rock parts, as well as leadsheets. Each of the music fonts can be paired with any of hundreds of text fonts to create a gorgeous, customized score. Petrucci Sonata Golden Age
