Tempo describes the speed of the beat. Italian terms range from very slow (largo, grave) through slow (lento, adagio), moderately slow (andante, andantino), moderate (moderato), and fast (allegretto, allegro, vivace, presto, prestissimo). A metronome marking such as quarter note = 88 specifies exact beats per minute. Gradual tempo changes include accelerando (speeding up) and ritardando (slowing gradually); ritenuto indicates an abrupt slowdown; rubato allows flexible timing. Dynamics indicate relative loudness from pp (pianissimo) to ff (fortissimo), with mp and mf in between. Crescendo and decrescendo hairpins show gradual changes; subito indicates a sudden change; sforzando (sf or sfz) marks a sudden accent on a single note. Terraced dynamics contrast a loud passage immediately with a soft one. Articulation symbols include staccato dots (detached), tenuto lines (sustained), slurs (connected phrasing), and marcato accents (emphasized attack). In sight-singing, maintain steady tempo unless a change is notated, and apply the indicated dynamic and articulation markings.
A score shows mp, then a crescendo hairpin, then ff, then subito p. Describe the dynamic shape of that passage in plain terms.
