We will now use the concepts we have discussed to analyze a short piece by the Russian composer Pyotr Il’yich Tchaikovsky (1840-1893) called French Song.

The first step is to determine the key of the piece. We should first look at the key signature. In this case the key signature (a) has two flats. This means that is either B flat major or G minor. By looking at the first (b) and last (c) measures we see that it starts and ends with a G minor chord. We can then conclude that the piece is in the G minor key:

The G minor key can also be determined by the use of the F sharp note in the D major chord just before the last chord. D major is the dominant chord of the G minor key.

Once we know the key of the piece we can identify chords, inversions, degrees and harmonic functions. Let's take a look at the G minor key's chords. Uppercase roman numerals are used for major chords and lowercase roman numeral for minor chords. The o is used to identify the diminished chord:

In minor keys, the V and VII degrees are commonly altered. As a result we can have more than seven chords. In this case we have only used the raised seventh degree in the V and VII degree chords.

Let us now do a complete analysis:
