In this course, we will be studying many styles of music, but all of these will have roots in the harmonic and melodic practices of the common practice period. The common practice period is generally considered to include Western art music from the Renaissance through the Romantic eras, but any music that that grew out of this tradition–including almost all popular music today–can be analyzed using the tools we will study for common practice harmony.
By the time musicians begin formally exploring music theory, they likely are familiar with basic music notation–treble and bass clefs, staves, ledger lines, and accidentals–due to time spent performing. If you are uncomfortable with any of aspect of these concepts, you can review by reading the explanations under the Further Reading section of Discussion 1a.
Even though most college music students are familiar with reading music, most are partial to the clef associated with their primary instrument or voice-part. It is vital that musicians be fluent in not only the two most common clefs–treble and bass–but also with two additional clefs: alto clef and tenor clef. Alto and tenor clefs are often used by instruments such as viola, cello, trombone, and bassoon. They alleviate the use of ledger lines in the extreme registers of an instrument and appear regularly in even the most elementary music.
Treble clef is sometimes referred to as a G-clef, and bass clef can be called an F-clef. Alto and tenor clefs are known as C-clefs. So let’s piece together the notes and octave relationships between the clefs as well as why the clefs have these alternate names.
In the examples below:
Knowing this, use these examples to find:
Clefs have secondary names because each clef is centered around the pitch in its name. The bass clef’s dots surround an F, and the two C-clefs are centered on middle C. Treble clef, however, not only encircles the G at the center of its spiral, but it evolved from a stylized G. For a well-researched, short article on the evolution of clefs, I suggest reading Jimmy Stamp’s The Evolution of the Treble Clef from the Smithsonian website.
The octave relationship for each clef is the most important thing you can remember from this discussion, and the easiest way to demonstrate this is to look at where middle C sits on each clef. Below, you can see the note names for the lines and spaces of each clef, and middle C is highlighted at the beginning of each staff.
When asked about their methods, past students suggested working on clefs via:
