Acoustics of Musical Instruments and Human Voice
FEKT-BPC-ANHAcad. year: 2020/2021
The subject deals with the five basic shapes of acoustic or electronic/virtual wave, the registers of musical instruments regarding spectral saturation and their loudness, the mixing of sound colours, masking and categories of the dynamic behaviour of a tone. Furthermore, the traditional as well as modern tone systems are characterized from the viewpoint of interpretation, types of listening rooms regarding their acoustics, the most frequent types of chamber bodies, variants of dispositions of a symphonic orchestra (European, American, etc.), the most common forms of vocal bands, and the most common configurations from other genres (rock, jazz, country).
Learning outcomes of the course unit
The student will be able to:
- describe an ADSR sound envelope,
- name basic tonal systems and characterize them in terms of interpretation,
- describe keyboard, string, and wind instruments, both wood and brass, in terms of interpretation,
- describe solo voice singing and vocal bands,
- describe chamber bodies and bands in the area of popular music and symphonic orchestras and describe their most frequent configurations.
The knowledge of basic concepts of musical acoustics, capabilities and limitations of musical instruments, and the influence of room acoustics on the interpretation of music.

Planned learning activities and teaching methods
Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.
- Lectures provide the explanation of basic principles, subject methodology, examples of problems and their solutions. They are complemented with listening to recordings.
- Laboratory exercises support practical acquiring of themes presented at lectures. Active participation of students is needed.
Participation at lectures is recommended. Participation at other ways of instruction is checked.
Assesment methods and criteria linked to learning outcomes
Evaluation of study results follows Rules for Studies and Examinations of BUT and Dean's Regulation to the Rules for Studies and Examinations of BUT. Credit is given for creation of stereophonic recording of sound of musical instrument.
Language of instruction
1. Summary of the course Fundamentals of Musical Acoustics.
2. ADSR sound envelope.
3. Tonal systems: pythagorean, natural, tempered.
4. Tonal systems: exotic, micro-interval-based, etc.
5. Keyboard instruments.
6. String instruments.
7. Wood instruments
8. Brass instruments.
9. Solo voice.
10. Polyphonic singing.
11. Chamber bodies.
12. Popular music group setups.
13. Symphonic orchestra.
The aim of the course is to familiarize students with the basic shapes of acoustic and electronic waves, registers of instruments, the mixing of sound colours, tonal systems, types of rooms in terms of their acoustics, types of music bands and groupings including the most common configurations.
Specification of controlled education, way of implementation and compensation for absences
To obtain the credit it is necessary to complete at least 10 exercises during semester. Other forms of the checked instructions are specified by a regulation issued by the guarantee of the course and updated for every academic year.
