Music Analysis













Hi all, I have choosen this piece fairytale (童话) to do my musical analysis. This is a chinese piece sang by Guang Liang (Chinese Singer), however this is not the original version of the piece. I could not get the midi file for the above score, so for listening purposes, you can check out the following link: http://www.youtube.com/watch?v=ABenWi0DlIU&feature=related. It is pretty close to the chosen score.
Harmonic and Functional analysis
  • The opening of this piece is in F major and it stays in this key till the final chorus where it modulates once to G major, and once more to A major. The piece begins with a four bar intro in F major. The chord progression is:
I---vi---IV---V,
and so the functional analysis for this part would be
T---PD---D.
  • The melody starts on the fith bar with a preceding upbeat of one and a half counts, and this pattern is repeated throughout the entire piece. The chord progression from bars 5 to 8 would be similar to that of the intro:
I---vi---IV---V,
and similarly the functional analysis would also be
T---PD---D.
This is again repeated in the consequent phrase from bars 9 to 12.
  • From bars 13 to 16, a new theme is introduced and the chord prgression is now:
iii---vi---IV---V,
the iii in this case seems to act as a tonic substitute. The functional analysis for this four bars would still be T---PD---D. This would again be repeated in bars 17 to 20.
  • The chorus to this piece begins on bar 21 where the chord progression is mainly two to a bar instead of one to a bar as in the first 20 bars. The chord progression for this part of the music is:
I---iii(6/4)---vi---I(6/4)---IV---V---I.
The functional analysis for this part would now be:
T---PD---T---PD---D---T.
  • The chorus then continues with:
IV---V---I---iii(6/4)---vi---IV---V---IV.
  • The last chord IV is actually for the music to enter a bridge instead of ending it off in a perfect cadence as can be seen in bar 63 where the final chorus ends on the tonic chord as what should have originally been intended for bar 28. So summing, the functional analysis for the chorus is:
T---PD---T---PD---D---T---PD---D---T---PD---D---(T)
The last T in parenthesis would actaully mean the intended chord for the chorus.
  • Moving on to the analysis of the bridge part. As mentioned earlier, the chorus was supposed to end on the tonic, however it ends off on the subdominant, a chord IV which also signifies the start of the bridge. The chord progression here would be as follows:

IV---I(6)---ii---I---IV---I(6)---ii---V

If we look at it further, we can actually say that the chorus ends midway through the bridge (i.e bar 28). The two opening chords of the bridge section can actually act as a form of tonic expansion and then rounds the whole chorus off with a plagal cadence ending, except that since a chord I in first inversion is used, the cadence at that point does not sound like a full closure. A further analysis of the bridge section would show that it ends on an imperfect cadence, which actually allows the piece to go back to the second theme(13-20) introduced at the beginning. This second theme is exactly the same as the original in terms of chords and functional analysis. So the functional analysis for the bridge section would be:

PD---T---PD---T---PD---T---PD---D

From here, we can actually see that the entire bridge section would be a tonic expansion by itself.

  • The last section of concern here would be the final two of the piece since it would be irrelevant to comment further on the other parts as they are repeated. Both these chorus are actually modulated, and are modulated by step. In the last two beats of bar 47, we can see that the composer starts on a submediant and uses a G flat to prepare for the modulation to G major. A chromatic pivot chord in the form of F# is used here. The dominant of G major which is D major is first heard as a secondary dominant i.e V/ii. The next bar then shows a complete modulation to the key of G major which we can draw from the key signature as well as the G chord used.
  • A similar method is used for the next chorus where it modulates to A major. This time round however, the chromatic pivot chord is G#. As similar to the above, the secondary dominat of the new key is heard first before we here the actual modulation. The chord and functional analysis for this part would be the same as the beginning.
  • The piece ends in A major with a two bar coda which we can consider as an extension ofthe last chorus. The chorus ends at the first two beats of bar 63, on a perfect cadence. However, the piece does not end there it carries on further to chords IV and V before ending on I. It thus can be seen that the final two bars are actually a tonic expansion of the final chorus in the form:

T---PD---D---T

Phrase Structure Analysis
  • Looking at bars 5 to 8, the first voice part enters with a sentence. The sentence structure would be S,S,L . Bearing in mind that the sentence actually begins on the upbeat from bar 4, we can see that each S is represented by 4 crotchet beats, and the L would be represented by 8 crotchet beats. This would form the antecedent phrase, with a half cadence closure. The next 4 bars would be in a similar SSL pattern and it forms the consequent phrase. However the consequent period does not display any complete closure in terms of cadence ie. the cadential closure is still a half cadence, similar to bars 5 to 8. This 8 bars would form the antecedent period.
  • The consequent period is formed by bars 13 to 20. Similarly, bars 13 to 16 would form the antecedent phrase with a SSL structure similar to that of bars 5 to 8. The consequent phrase would be from bars 17 to 20 with a similar SSL structure. The cadential closure for this part would be similar to that of the antecedent period in that both phrases again close with a half cadence, or there is no distinction in the type cadence used. The whole structure from bars 5 to 20 now forms a double period:

------------------------------------------Double Period

-------------------------------------------(Bars 5 -20)

------------Ant Period------------------------------------------Conseq Period

----------(Bars 5 - 12)-------------------------------------------(Bars 13 to 20 )

Ant phrase ---------Conseq Phrase -------------Ant Phrase ----------------Conseq Phrase

(Bars 5 - 8) -----------(Bars 9 - 12) ------------(Bars 13 to 16) ---------------(Bars 16 to 20)

  • The chorus would form a new period by itself. The 8 bars can be divided equally into an antecedent phrase and a consequent phrase. The Antecedent phrase wouldbe from bars 21-24 with the one and a half beat, upbeat in bar 20. It ends after the first two and a half beats of bar 24. The consequent phrase would be from that point all the way to the first two and a half beats of bar 28 where it closes with a plagal cadence as aforementioned. Within the phrases we can see a short, short, long structure in each phrase. Each short sentence is about four crotchet beats while each long sentence would be about eight crotchet beats long. Hence the chorus would be a simple period with an antecedent and consequent phrase:

------------Ant Period

-----------(bars 21-28)

Ant phrase ---------Conseq Phrase

(bars 21-24)---------(bars 25-28)

  • Well, i thats all for now, will be back with more posts or edits.

  3. Nice song you've got there=)
    Here's some of my comments.

    Harmonic/Functional analysis:

    General point: it's not very clear which function corresponds to which chords. eg. for bars 21 onwards, there were 7 chords with 6 functions. i wasn't sure if you interpreted iii(6/4) in this case as a tonic substitute or as a PD. eg. T----PD T or T PD----T for I-iii(6/4)-vi-I(6/4).

    Bars 13-16
    I think chord iii in bar 13 plays the role of a dominant substitute, and chord vi the role of a tonic substitute. Hence the functional analysis of D-T-PD-D.
    To understand this, we could try viewing b13-14 as a modulation to Dm. then Am to Dm would somewhat suggest a v-i perfect candence (i don't mean the actual Dm perfect cadence which is V-i) when looking the two bars independently.
    Now looking at the chords back in F major, it would also make sense for iii to be a Dominant substitute (iii and V share the notes C and E).
    With this in mind, chord vi in this case would more appropriately suit the function of a Tonic substitue rather than PD, being right after the Dominant substitute (it also can be noted that I and vi share the notes F and A). Another way to look at it, if we were to replace chord vi with chord I(Tonic), it would sound more harmonically correct than if we were to replace chord vi with chord IV(Predominant).

    Bars 21-24
    I interpret the four chords in bars 21-22 (I-iii-vi-I) as a Tonic expansion rather than T-PD-T. One reason is if we were to take a look at the melody in these 2 bars, it is evident there is a strong tonic feel. It would also be harmonically sound if we were to replace the chords in these 2 bars to just chord I. Hence, the entire phrase would be T-PD-D-T.

    Bars 25-28

    I disagree with regards to 'The last chord IV is actually for the music to enter a bridge instead of ending it off in a perfect cadence'.
    Instead, bar 28 could serve as both the ending of the chorus in a perfect cadence, as well as the start of a bridge. (eg. the ending of a phrase overlapping with the start of a new phrase). One thing to suggest this is the F note in the melody of bar 28 ending the phrase. It is held for 2 beats to sound together with chord I.
    In fact, I feel b28's primary role is to end off the chorus nicely with a perfect candence (closure), while being the 'start of the bridge' is secondary.

    I don't understand your functional analysis for this segment. (There are 11 functions for 8 chords). I agree with your chordal analysis, with the inclusion of chord I at the end.
    Nevertheless, this is the way i interpreted bars 25-28:
    IV-V-I-iii-vi-IV-V-IV-I
    PD-D-T------PD-D-T---

    The first tonic expansion, comprised I-iii-vi, with iii as a passing chord.
    I interpreted last two chords(IV-I b28) as a tonic expansion. We could also intepret these two chords as
    6-5
    I 4-3
    like a neighbouring 6/4. (In this case the common tone would be the F held in the melody).

  4. Phrase Structure analysis:
    You mentioned b5-20 forms a double period, however, I think it would be more appropriate to think of b5-12 and b13-20 as separate subsections. This is because b5-12 and b13-20 are entirely different and b13-20 doesn't sound like an answer to b5-12. The accompaniment is of a totally different style as well.

    I agree of ur SSL analysis of b5-8. However, i feel that the SSL analysis is totally applicable to b13-20.
    I view the phrase structure as just 4 two bar (long) subphrases (eg. combine the two short subphrases into 1 subphrase. This is because the first short subphrase you indicated does not sound at all like the 2nd short subphrase ( especially in the second phrase at b17-18). It doesn't sound like the two short subphrases were meant to be a sequence.
    I do agree that b13-16 and b17-20 has an antecedent-consequent relationship though.

    Chorus:
    As above, I disagree that each phrase has a ssl structure, especially in b25-26 in the 2nd phrase. It is evident that b25-26 is just a long phrase. Comments are same as for b13-20.

    Other musical observations:
    I noticed the chords in the main verses are mainly played in the root position whereas in the chorus, some chords are deliberately inverted to give a smooth flowing bass line. eg. b21-23 features a descending bass line.

    Maybe you would like to state the overall structure of the piece at the start.

    All said, I can see you have put in effort in analysing the piece. Good job and jiayou=)

  5. Hello..

    The melody starts in the 2nd half of bar 4, not bar 5.

    Most of the pre-chorus sections end on a V chord, which I feel should actually be a tonicization to the dominant: V/V (C major in F major). This is because the leading notes are D in the melody, and Bb in the accompaniment, and both notes tend to resolve to C. A tonicization would better explain why there is a feeling that the progression has been partially resolved despite the imperfect cadence.

    You mentioned IV---V---I---iii(6/4)---vi---IV---V---IV (bars 20-27), where the last chord IV is for the music to enter a bridge instead of ending it off in a perfect cadence. To me the chord IV should actually be a passing 6/4 in this manner: I 6/4 - 5/3.

    Intriguingly, this ending is then exploited immediately after it supposedly resolved itself (bars 28-29) when the composer tonicizes it to the dominant yet again (bars 29-30). This could have been due to consistency as mentioned earlier about each section in the pre-chorus ending with a V chord. This tonicization allows it to resolve to the bridge section (bars 12-17)

    You mentioned that within the phrases of the chorus we can see a short, short, long structure in each phrase. However, Bars 22-23 don't follow a short-short-long sentence structure to me.

    Yup that's all I can come up with now. Still got tons of homework and tests to study. ARGH. Anyway, a suggested improvement for your analysis would be to scan in the pictures of your music score with the analysis done on it so that it will be easier for reference, as I had quite some difficulty in locating which parts you were referring to.

    Finally,
    GY

  6. Sorry there's an error in my second point:

    "To me the chord IV should actually be a passing 6/4 in this manner: I 6/4 - 5/3".

    Should be "...CADENTIAL 6/4 in this manner: I 6/4 - 5/3".

  7. Hi Yung Chuen,

    Good work here. The detailed commentary can be more succinctly presented though.

    The main issue I wish to address is the progression at b. 28-29. Essentially, it is a plagal expansion of the tonic (IV-I with I6-ii as passing harmonies; note the parallels between ii-I!) The structural cadence for this phrase, however, is a perfect cadence formed with the chord V in b. 27. In other words, think of the IV-I6-ii as delaying the expected I.

    Fawnfawn’s hearing of bs. 13-14 as a tonicization of D minor is invalid since there is no applied leading-note (C#). One may take the Am chord (iii) tobe a tonic substitute, as you have interpreted. For bs. 21-22, she does have a point about it hearing it as a tonic expansion. A I-vi-V would be typically parsed as T-PD-D, here with the harmonized passing notes in the bass, one may also simply indicate the whole progression as TD.

    Fawnfawn also questioned your double period reading. Again, there is indeed a sense that the second period is contrasting but this in itself does not invalidate your double-period interpretation. Recall the parallel vs contrasting period distinction. I also agree with your phrase analysis of the chorus, there is no need to subdivide the 4-bar phrases there since there are no cadences at bs. 22 & 26.

    Re GY’s comment about your numbering system, he is doing it literally. However, yours is the more common practice: that is, we normally subsume the anacrusis under the complete bar it leads to. (GY, please also note that your idea of leading-note is also faulty: it must be the seventh scale degree that is a semitone below the tonic; in this connection, b7 is sometimes referred to as the subtonic. If you are just talking about general voice-leading or even just melodic tendencies, do not use the technical term “leading note”.)
