The noncommutative symmetric functions $\textbf{NSym}$ were first defined abstractly by Gelfand et al. in 1995 as the free associative algebra generated by noncommuting indeterminates $\{\boldsymbol{e}_n\}_{n\in \mathbb{N}}$ that were taken as a noncommutative analogue of the elementary symmetric functions. The resulting space was thus a variation on the traditional symmetric functions $\Lambda$. Giving noncommutative analogues of generating function relations for other bases of $\Lambda$ allowed Gelfand et al. to define additional bases of $\textbf{NSym}$ and then determine change-of-basis formulas using quasideterminants. In this paper, we aim for a self-contained exposition that expresses these bases concretely as functions in infinitely many noncommuting variables and avoids quasideterminants. With the exposition out of the way, we look at the noncommutative analogues of two different interpretations of change of basis in $\Lambda$: both as a product of a minimal number of matrices, mimicking Macdonald's exposition of $\Lambda$ in Symmetric Functions and Hall Polynomials, and as statistics on brick tabloids, as in work by Eğecioğlu and Remmel, 1990.
