    362880 ways

    Step-by-step explanation:

    In this case, the order does matter therefore to know how many ways it can be aligned, we must resort to permutations.

    The formula for permutations is:

    P = n!

    we know that there are 9 trumpet players, therefore:

    P = 9!

    P = 362880

    So there are 362,880 ways to line up
