;; 1. Use the 'print' command to print each the following things

; integer
; ratio 
; float
; MIDI key number in 5th octave (the octave above the middle C octave)
; floating point key number that sounds 75 cents above Middle E (E4)
; floating point key number that sounds 50 cents BELOW Middle E
; ratio representing one beat
; ratio representing two-thirds of a beat
; ratio representing thee and two fifths beats
; strings representing the note names of
;    key number 33  
;    c-sharp in the third ocave 
;    quarter tone above c-sharp in the third octave
;    b-flat in the zero octave
;    f-double-sharp in the seventh octave
;    d-natural in the third octave
; boolean false
; boolan true
; string
; list containing the names (symbols) of three dead composers
; list representing a twelve-tone row
; list of three triads, where each triad is a list of three key numbers

;; 2. write a 'print' expression that:

; adds two integers
; adds three to the divison of one by three
; raises 10 to the third power
; returns the modulus of -1 and 12 

;; 3. use the print statement to determine the true or falsity of each
;; of these propositions:

; 1 is EQUAL to 2
; 1 is NOT EQUAL to 2
; 1 is LESS THAN 1
; 1 is GREATER THAN OR EQUAL to 1
; true AND true
; 1 is LESS THAN 2 AND 4 is NOT EQUAL to 5
; false OR false OR true
; false OR true AND true
; NOT true OR false
; NOT NOT true

;; 4. explain why 'NOT TRUE' is the same as 'FALSE' 

;; 5. execute each of these two commands 10-15 times, then describe
;; the behavior of the function based on your observations: what is
;; the relationship of random's input value to its output value?

random(3)

random(3.0)

; explain here:



; 6. why does ran(3.0) gives us so many more possible values than
; ran(3) explain:

; 7. change this sexpr so that it will randomly print 5 6 or 7 instead of
; 0 1 or 2.

random(2)

; 8. write a print statement using random that chooses any integer
; key number in the 6th octave

; 9. evaluate this define statement. then use the var[ ] notation to
; separately print each element from the variable's list

variable test = {a b c d e}

; 10. use print command to print a list constructed by calling the
; list(...) function with the following inputs: the integer 10, a list
; using {} with two elements in it, the addition of 5 6
