Notation of Frequency
|
Frequency
Remember that music and melodies are always fluctuating between high and low (the Hz are always changing) I.E. We would not usually see a song where there is only 1 note for the entire tune Refer to the tune on the right. Notice the Melody ... starts high, goes down, goes back up ETC. (Remember when you were composing your melodies, I said to keep it simple - WE SEE SIMPLE MELODIES WITH ONLY A FEW NOTES ALL THE TIME IN MODERN POPULAR MUSIC) Using the staff and musical notation we are able to put a name/label for each of those pitches and also a symbol for what it looks like (These symbols are ALMOST universal - people all over the world read this same language) |

The Following concepts are meant to make reading frequency notation Easier! In a sense they are shortcuts, which can be a pain to memorize but make the reading easier!
Accidentals
|
Accidentals are used for altering a pitch
Flats and Sharps Raise / Lower A note by a 1/2 Step SHARP - UP 1/2 Step FLAT - DOWN 1/2 Step A NATURAL Accidental cancels out any alteration made by a flat/sharp previously ***** Because we have been writing out scales Ascending, we have been using mostly SHARPS****** |

Key Signatures
We have been figuring out scales using a formula of Half / Whole Steps
In Notation, Key signatures are used so we don't need to write out flats and sharps when we are staying in one key - Or based around one scale
Example - Your assignments are all in the Key of C - Most likely your melodies all use notes from the key of C

Instead of Writing out the sharp every time we hit sharp note, We put them in the key signature
In a Given piece of music, at the beginning before we ever see a note, we see a Key Signature and Time Signature
Both of these carry through the piece unless we get a new Signature in the middle
A Change of Key in the middle of a song is known as a MODULATION
In The Example below, we are in Ab
See the Key signature : Bb Eb Ab Db
Here , any time we see any of these notes they are flatted

Accidentals are used when we hit notes Outside of the Key Signature
Example : If you did your project in C and use Eb in your Melody, it will have a Flat accidental in from of it in the notation

Rhythm
Where with frequency we get a variety of both high and low notes, when dealing rhythm we get an assortment of Long and Short notes.
Refer to this other Blink 182 song. In all parts (melody/harmonic accompaniment/rhythm) we see a range of note durations.

See Below the Notes we Talked about last class....
These notes only cover rhythms of an even number of beats, or even number of half beats.
What if we want 1.5 Beats?
or 3 Beats?
What if we are in 3/4 Time?

Dotted Rhythms
Adding a Dot to a note alters it's rhythm by a ratio of 1.5
in other words, it gives it an extra HALF of whatever it's value was
In Theory any note can be dotted, but we Most commonly see it with Quarter Notes and Half Notes
