First Term

During this term we have learnt a lot of new vocabulary. We have focus on the qualities of sound. There are four qualities pitch, intensity, duration and timbre.


PITCH
Pitch: this quality of sound  distinguishes between high or low sounds. It is measure by wave frequency.
We should highlight some things about pitch:
Tuning fork: it is an object used before playing an instrument. It serves to tune.
Staff: group of five lines and four spaces where we write notes or other symbols.

Scale: sequence of notes.
Tone and semitone: unit for measure the pitch.

Clef: it is a symbol that indicates the name of the note. There are two types of notes:
  
* G clef:  we use it on the high register.








  * F clef: we use it on the low register.










DURATION
It is the quality of sound that distinguishes long or short sounds. It is measure by wave persistence.
Note values: symbols that represent the duration of sound value.
Rest: represent the duration of the silence.

Time signature: divide into equal parts and sets notes and rests values.
Length modifiers: prolong or extends the duration.
  * Dot: adds half of it value.
  * Ligature: adds up duration.
  * Fermata: extends interrupting the measure.
Tempo: speed of the performance of a musical piece:
  * Largo: very slow
  * Adagio: slow
  * Andante: calm
  * Allegro: fast
  * Presto/Vivace: very fast

Here it is video about an example of an overcoming.
For me it is really amazing.


We also have studied what is the sound, what is the noise, and what is the silence.
Sound: is produced when and object vibrates and it is transmitted
by sound waves. These waves are regular.
Noise: is a bad unpleasant sound. It is also transmitted by waves but these waves are irregular.
Silence: it happened when there is no sound.

Here is an example of a quite unusual room where you can´t hear anything and you can't produce echo.

For me this video it´s a bit weird and I think that it is amazing what we can do
