The Module
• Five Blocks:
– Prelude
– Investigating Sound (what is sound?)
– Musical Instruments (how is sound made?)
– Sound Processes (how is sound manipulated?)
– Project
TA212 The Technology of Music
Block 1: Prelude
• Making Sense of Music
• Listening to Music
• Maths for Music
This block is designed to bring everyone up to the same basic level in both
Music Theory and Maths.

Block 2: Investigating Sound
•

•
Sound Basics
Sound Shape and Colour
Sound and Time
Sound and Space
Sound and the Listener
Sound Capture and
Recapture
waves, frequency, wavelength
timbre, temperament
more music theory
reverberation
listening, perception
microphones, amplifiers
TA212 The Technology of Music
Waves
pressure
• Sinusoidal Pressure Waves
• Frequency
– How many times per second
• Amplitude
– How big
wavelength
TA212 The Technology of Music
The Octave
• Double the frequency
• Notes an octave apart have the same name

Harmonics
• Modes of Vibration
• Harmonic Series
– frequencies: 100, 200, 300, 400, 500...
– Pitches
– Most higher harmonics are out of tune!
TA212 The Technology of Music
Reverberation
• Many Paths
• Long paths
– have more reflections
– take longer to arrive
– are are quieter when they arrive
TA212 The Technology of Music
The Human Ear
• Outer ear
– Collects sound
• Middle ear
– Impedance Coupling
– Acoustic Reflex
• Inner Ear
– Detects sound

Impedance Matching
• Impedance
– Property of all electronic circuits
• Get it wrong and you get distortion

Block 3: Musical Instruments
•
•
•
•
What is a Musical Instrument
Making sound
Families of Instruments
How do Instruments Work?
strings, pipes, pitch
orchestral, electronic, voice
TA212 The Technology of Music
String Harmonics
• Many different standing waves
• The sounds they produce are the harmonics of the
string.
TA212 The Technology of Music
Wind Harmonics
open pipe
stopped pipe
NOTE: A conical pipe (such as an oboe) behaves like a pipe open at both ends
TA212 The Technology of Music
Cristofori Action
TA212 The Technology of Music
Vowels
• Shape of the vocal tract
• Each shape emphasises different frequencies
• The frequencies which are emphasised are called
Formants
TA212 The Technology of Music
Electromagnetic Induction
electricity
magnetism
motion
• Given any two, the third is produced
electricity + magnetism = motion (electric motor)
magnetism + motion = electricity (generator)

Block 5: EMA (The Project)
• Part 1: An essay about a musical instrument
– Includes research outside the course material and
analysis of the sound of the instrument using the
course software.
– Refer to Block 3 for the kind of information expected
– Choose an “acoustic” instrument.
• Part 2: Desktop Sound
– This may include creating sound samples and using
them to realise a few bars of music presented as a
score.
