Music Block-List

Block	Description
	Play a short melody of notes composed in a string. melody: a string which contains the notes of the melody. tempo: a number which is the rate to play the melody at in beats per minute.
	Play a musical tone through pin `P0` of the micro:bit for as long as you say. `frequency` is the number of Hertz (how high or low the tone is). `ms` is the number of milliseconds that the tone lasts
	Play a musical tone through pin `P0` with the pitch as high or low as you say. The tone will keep playing until you tell it not to. `frequency` is a number that says how high-pitched or low-pitched the tone is. This number is in Hz (Hertz), which is a measurement of frequency or pitch.
	Rest (play no sound) through pin `PO` for the amount of time you say. `ms` is a number saying how many milliseconds the micro:bit should rest. One second is 1000 milliseconds.
	Set the volume for the sound synthesizer. the volume of of the sounds played to the sound output. The volume number can be between 0 for silent and 255 for the loudest sound.
	Get the current volume level of the sound synthesizer. A number that is the current volume level of output from the sound synthesizer. The value can be between 0 for silent and 255 for the loudest sound
	Stop all the sounds that are playing right now and any others waiting to play. If you play sounds or sound effects more than once, the sounds you asked to play later have to wait until the sounds played earlier finish. You can stop the sound that is playing now and all the sounds waiting to play with stop all sounds.
	Makes the tempo (speed of a piece of music) faster or slower by the amount you say. bpm is a number that says how much to change the bpm (beats per minute, or number of beats in a minute of the music that the micro:bit is playing).
	Makes the tempo (speed of a piece of music) as fast or slow as you say. bpm is a number that means the beats per minute you want (the number of beats in a minute of the music that the micro:bit is playing).
	Returns the duration of a beat in milli-seconds. Beat Fraction means fraction of a beat (BeatFraction. Whole, BeatFraction. Sixteenth etc)
	Finds the tempo (speed of a piece of music). A number that means the beats per minute (number of beats in a minute of the music that the micro:bit is playing).
	Begin playing a musical melody through pin `P0` of the micro:bit. melody: A built-in melody or an array representation of a melody you wish to play. options: the play option for the melody. once: play the melody in the foreground one time forever: play the melody in the foreground and keep repeating it once in background: play the melody in the background one time forever in background: play the melody in the background and keep repeating it.
	Stop playing a musical melody. options: specify which melodies (foreground, background or both) to stop: all: stop all melodies foreground: stop the foreground melody background: stop the background melody
	Raises events for melodies or music events. Value the kind of event Handler the code to run when the event is raised.
	Play a sound that is generated from a sound expression. sound: a string that is the sound expression for the sound you want to play. mode: the play mode for the sound, either until done or background.
	Get a sound expression string for a built-in sound effect. sound Expression: A sound expression name. The available effects are: giggle, happy hello, mysterious, sad, slide, soaring, spring, twinkle, yawn.
	Create a sound expression string for a sound effect. A sound expression is set of parameters that describe a Sound that will last for some amount of time. These parameters specify a base waveform, frequency range, sound volume, and effects. Sound data is created as a Sound object and can then be played to the speaker, headphones, or at an output pin. wave Shape: the primary shape of the waveform: sine: sine wave shape saw tooth: saw tooth wave shape triangle: triangle wave shape square: square wave shape noise: random noise generated wave shape start Frequency: A number that is the frequency of the waveform when the sound expression starts. end Frequency: A number that is the frequency of the waveform when the sound expression stops. start Volume: A number the initial volume of the sound expression. end Volume: A number the ending volume of the sound expression. duration: A number the duration in milliseconds of the sound expression. effect: An effect to add to the waveform. These are: tremolo: add slight changes in volume of the sound expression. vibrato: add slight changes in frequency to the sound expression. warble: similar to vibrato but with faster variations in the frequency changes. interpolation: controls the rate of frequency change in the sound expression. linear: the change in frequency is constant for the duration of the sound. curve: the change in frequency is faster at the beginning of the sound and slows toward the end. logarithmic: the change in frequency is rapid during the very first part of the sound.
	Enable the speaker on the micro:bit to play music and sounds. enabled: A boolean value that is true to enable the built-in speaker, or false to send sounds to the pitch pin.
