By the end of this lesson, students will be able to:
ID and construct diatonic triads in root-position or inversion using Roman numeral notation.
Indicate the chord quality of triads built on each diatonic scale degree in major and minor.
Rewrite a chord progression using lead sheet notation into Roman numeral notation.
Explain the different musical contexts and applications for lead sheet and Roman numeral notation.
"Roman Numerals" (OMT) - skip the section on 7th chords
"Triads within Tonality" (T. Rush, Handout)
Optional Review: "Figured Bass Inversion Symbols" (MT21st) - see the symbols for triads.
The Sound of Roman Numerals: Pick one or two of the following sites to experiment with the sounds of chords built on different scale degrees.

Roman Numerals vs. Lead Sheet Notation: In terms of the lead sheet notation, all three of the following songs use different chords. It looks like a different progression.
Listen to each of these songs:
Sam Cooke, "Another Saturday Night" (verse): C - F - C - G (in C major)
The Tokens, "The Lion Sleeps Tonight" (chorus): F - Bb - F - C (in F major)
Van Morrison, "Brown-Eyed Girl" (chorus): G - C - G - D (in G major)
Listen to each progression blocked on the piano by your instructor. Compare the sound of each. Now, analyze each progression above in terms of Roman numerals in the keys given.
How do Roman numerals and Lead Sheet notation provide different and similar information? Why might you choose to use one tool over another to communicate information to a performer or describe the harmony you hear in a song?
Roman Numeral Speed Challenge: Try the "Quizlet Live" Team challenge. Your instructor selects one of the Roman numeral ID flashcards from the practice section above, then selects the "Classic Live" option at the top of the page. Split up into teams and compete to see which team is the quickest at identifying Roman numerals!

Lead Sheet Notation into Roman Numerals: Go back to the Roman Numeral section in your anthology ("Roman Numerals from Lead Sheet Notation" section). For each song excerpt provided, rewrite the lead sheet notation as Roman numerals using the key provided.
Roman Numeral ID in Repertoire: Continue on to the next section in your anthology, "Roman Numeral ID: Triads Only." For each song excerpt, notate the Roman numerals on the lines provided below the staff. Ignore any notes in parentheses or any chords that have been provided.
