In this course we have covered all you need to rain your ears to recognise the musical elements useful to a sound engineer. Of course if you are able to do more that what outlined in this course, it is all the better.

Let's summarise what has been covered so far.

We have defined the concept of note as a sound of a specific frequency, and as a symbol to represent such sound.

We have learnt how different pitches are represented on a staff, and how a clef determines the pitch of the notes on a staff. We have also examined how notes and rests of different lengths are represented with regard to the meter and the tempo of a song.

The tempo of a song is expressed in beats per minute or BPM, and knowing the BPM allows us to determine the exact length of a note in seconds.

We have seen that all the 12 steps that are part of an octave are related to each other in intervals: an interval is the 'distance' between two notes. An interval expresses an mathematical relationship between the frequencies of two notes. Combining selected intervals originates a scale: different scales are used to give a song a specific mood or feeling. Combining notes subsequently in time forms the melody of a musical piece.

Notes can also be combined vertically (more notes in the same instant), to form chords, or the harmony of a musical piece. Different intervals in a chord can convey different moods: we have examined major, minor, diminished, suspended, major seventh and minor seventh chords.

We have discussed the most common instruments employed in pop music and their role, and briefly mentioned their frequency range.

Finally, we have examined different parts of a pop song and how they are combined together. We have also seen examples of these parts put together in real songs.

We hope you understood the purpose of these classes and that you will develop your listening skills in the test section. The ability that you will develop by completing the whole set of tests will be of great help in your work.
