(a) The time signature that suits a walking bass line is 4/4. [1] A walking bass line consists of a continuous stream of crotchets (quarter notes), each on a successive beat, "walking" through the harmony one note at a time. The steady four-beat pattern of 4/4 time provides the framework for this style of bass playing, which is fundamental to jazz performance.

(b) The term for emphasis on beats 2 and 4 is syncopation (or off-beat accents). [1] In standard 4/4 time, beats 1 and 3 are the naturally strong beats. When the emphasis shifts to beats 2 and 4, this displaces the expected accent pattern, creating syncopation. In jazz, the rhythm section (particularly the drummer on the hi-hat) typically marks beats 2 and 4, which is known as the backbeat and gives jazz its characteristic swing feel.

(c) Two features of the saxophone solo (any two from the following): [2]

1. Use of swing rhythms - the soloist plays pairs of quavers unevenly, with the first slightly longer than the second, creating the characteristic "swung" feel of jazz.
2. Use of chromatic notes or blue notes - the soloist incorporates notes outside the main key, particularly the flattened third, fifth, or seventh degrees of the scale (blue notes), adding expressive tension and the distinctive "bluesy" sound of jazz.
3. Varied dynamics - the soloist uses changes in volume for expressive effect, perhaps playing quietly in one phrase and building to a loud climax in the next.
4. Ornamentation such as slides or bends - the soloist uses pitch bends, slides between notes, or other ornamental techniques that are idiomatic to jazz saxophone playing.
