Make an interesting sound using any combination of mathematical functions.ĭon't use these examples make up your own.> Those who came before me lived through their vocations From the past until completion, they'll turn away no more And still I find it so hard to say what I need to say But I'm quite sure that you'll tell me just how I should feel today.

Use the table at to calculate the day of the year corresponding to your birthday.Ībout a quarter of the way through that year (090/365 = 0.247)Ĭorresponding to a frequency of 1959.247:

Use your birthday in years (since the beginning of year 1) as the frequency of a pure tone.

(Hint: what is the closest A note? How many semitones separate itĬalculate the difference geometrically, as a ratio, i.e. Multiply latter by frequency interval between A 7->C 8 The lowest note on an 88-key piano (A 0) and the highest (C 8)?

What is the range between the fundamental frequency of.

What is the frequency ratio of a half-octave?.

What is a musical fourth (P4) plus a musical fifth (P5)?.

Confirm that a frequency ratio of 4/3 corresponds approximately to P4: a musical fourth (five semitones).

Confirm that a frequency ratio of 3/2 corresponds approximately to P5: a musical fifth (seven semitones).

I imagine this is quite easy, but dont know how.

I would like Mathematica to produce a sound as soon as it ends (but not always, only when told so). (Hint: What is Power or 2^(1/12) or 2 1/12?) Post by Francisco Gutierrez Suppose I am running a simulation, and go on to work on another issue. There are 12 semitones in an octave (8 ve) on a piano, these are 5 black notes an 7 white notes.Don't forget that a pressure ratio needs to be squared. The human pain threshold is about 120 dB SPL.(Hint: What is the inverse operation to Log?) Multiply by 10 to convert from bels to decibels.) Use the //N Mma suffix to get a numerical answer. Alternatively, the suffix “ //N” (as in “ Log //N”) can be used to directly see numerical results.Use rational numbers (instead of integers), with a decimal point, to force numerical evaluation.(Mathematica commands are invoked with Shift+Enter.).The Mathematica function SoundNote represents a musical sound.
