Western music uses a musical scale with equal temperament tuning, which means that any two adjacent notes have the same frequency ratio r. That is, notes n and n+1 are related by fn+1 = rfn for all n. In this system, the frequency doubles every 12 notes-an interval called an octave.
a) What is the value of r ?
b) Orchestras tune to the note A, which has a frequency of 440 Hz. What is the frequency of the next note of the scale (called A-sharp)?

a multiple of the logarithm of the ratio of those two quantities. Une instance was the decibel as a measure of the loudness of sound. The other was the seismic moment magnitude scale as a measure of the intensity of earthquakes. Here is a third one. This one measures how different are the frequencies of two musical tones. The relevant unit is called a cent. If one knows the frequencies fi and f2 musical interval from fi to fo is...
CSC 142 Music Player You will complete this project by implementing one class. Afterwards, your program will play music from a text file. Objectives Working with lists Background This project addresses playing music. A song consists of notes, each of which has a length (duration) and pitch. The pitch of a note is described with a letter ranging from A to G. 7 notes is not enough to play very interesting music, so there are multiple octaves; after we reach...
Lab 2 (ADTs) 1) LockADT – Show the interface and all abstract methods LockDataStructureClass – Show the following methods: default constructor, overloaded constructor, copy constructor, setX, setY, setZ, alter (change the lock’s combination to the numbers passed) turn (use for loops to show the dial turning), close (locks the lock), attempt (tries to unlock the lock – calls turn( ), inquire (locked or unlocked), current (returns the number the dial is pointing to), toString LockClientDemoClass – You should have a...
