  11. The Course 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

  12. 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. TA212 The Technology of Music

  13. Block 2: Investigating Sound Sound Basics waves, frequency, wavelength Sound and Colour timbre, temperament Sound and Time more music theory Room Acoustics reverberation Sound and the Listener listening, perception Electronics microphones, amplifiers TA212 The Technology of Music

  14. Waves Sinusoidal Pressure Waves Frequency How many times per second Amplitude How big pressure wavelength TA212 The Technology of Music

  15. The Octave Double the frequency Notes an octave apart have the same name TA212 The Technology of Music

  16. Decibel Examples (SPL) Threshold of pain 130 dB Bass drum roll 106 dB Violin at player’s ear 85 dB Piano practice 70 dB Domestic Living Room 40 dB Empty Concert Hall 20 dB Threshold of Hearing 0 dB Investigating Sound -1, Page 45 TA212 The Technology of Music

  17. 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

  18. Reverberation Many Paths Long paths have more reflections take longer to arrive are are quieter when they arrive TA212 The Technology of Music

  19. The Human Ear Outer ear Collects sound Middle ear Impedance Coupling Acoustic Reflex Inner Ear Detects sound Outer Ear Middle Ear Inner Ear TA212 The Technology of Music

  20. Impedance Matching Impedance Property of all electronic circuits Get it wrong and you get distortion low  high high low  very high high low high Pre-amplifier TA212 The Technology of Music

  21. Audition TA212 The Technology of Music

  22. Audition TA212 The Technology of Music

  23. Block 3: Musical Instruments What is a Musical Instrument Making sound strings, pipes, pitch Families of Instruments orchestral, electronic, voice How do Instruments Work? TA212 The Technology of Music

  24. String Harmonics Many different standing waves The sounds they produce are the harmonics of the string. TA212 The Technology of Music

  25. 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

  26. Cristofori Action TA212 The Technology of Music

  27. Vowels Shape of the vocal tract Each shape emphasises different frequencies The frequencies which are emphasised are called Formants TA212 The Technology of Music

  28. Electromagnetic Induction Given any two, the third is produced electricity + magnetism = motion (electric motor) magnetism + motion = electricity (generator) electricity magnetism motion TA212 The Technology of Music

  29. Block 4: Sound Processes Desktop sound studio on your desktop Notation history, music printing Recording mechanical music, MIDI The Industry creating a recording, media, copy protection etc. TA212 The Technology of Music

  30. WAV File “RIFF” 4 bytes Size 4 bytes “WAVE” Format Chunk Data Chunk Size bytes TA212 The Technology of Music

  31. MIDI Connections MIDI In MIDI Thru Synthesiser “local off” switch MIDI Out TA212 The Technology of Music

  32. Media Bandwidth Telephone 3.4 kHz FM Radio 15 kHz CD 20 kHz MiniDisc 20 kHz but is always compressed! TA212 The Technology of Music

  33. Cubase TA212 The Technology of Music

  34. Block 5: ECA (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. TA212 The Technology of Music

  35. Assignments Submitted and returned electronically TMA00 optional used to prove that you have managed to connect into the eTMA system correctly 6 TMAs (Tutor Marked Assignments) EMA (End of Module Assessment) There is NO EXAM!! TA212 The Technology of Music

  36. TMAs TMA01 (20%) - Block 1 TMA02 (15%) - Block 2 part 1 & Audition part 1 TMA03 (15%) - Block 2 part 2 & Audition part 2 TMA04 (15%) - Block 3 part 1 TMA05 (15%) - Block 3 part 2 TMA06 (20%) - Block 4 TA212 The Technology of Music

  37. Substitution Substitution does not apply to this course If you fail to submit a TMA, you will get zero marks for that TMA. TA212 The Technology of Music

  38. To Pass... 40% overall for the TMAs 40% for the ECA (the project) TA212 The Technology of Music

  39. What Happens Next? Visit the Course Conference Read TMA01 so you know what to look for in the course text Form a study group to meet at a local pub to complain to each other about your tutor TA212 The Technology of Music
