What term describes a tempo that is a little faster than andante?

The term that describes a tempo slightly faster than andante is "andantino." In musical terminology, "andante" indicates a walking pace, generally around 76-108 beats per minute, conveying a moderate and relaxed speed. "Andantino" is traditionally understood to be a bit quicker than this walking pace.

While "allegretto," "moderato," and "vivace" denote faster tempos, they are not specifically characterized as being just a little faster than andante. "Allegretto" suggests a moderately fast tempo but is typically faster than andantino, while "moderato" indicates a moderate tempo but does not imply a speed close to andante. "Vivace" is much faster, indicating a lively tempo. Therefore, "andantino" is the most accurate term that reflects a slight increase in speed over andante, making it the correct answer.
