Coral language, On a piano, a key has a frequency, say f$0.$ Each higher key $($black or white$)$ has a frequency of f$0*$ rn$,$ where n is the distance $($number of keys$)$ from that key, and r is $2(1\mathrm{.}0/12\mathrm{.}0).$ Given an initial key frequency, output that frequency and the next $4$ higher key frequencies. Output all frequencies with five digits after the decimal point, which can be achieved as follows: Put frequency to output with $5$ decimal places
