    Part A

    Melody and chord dictation

    .

    (1) MELODIC TRANSPOSITION: Begin with sight singing the given melodies in several keys.Then follow the same sol-fa names, play the tunes in another key.

    (The 11-year old Liszt visited Beethoven. Liszt played some pieces, but the master gave no comment but

    asked him to transpose a Bach fugue at sight. Liszt played as asked without a mistake Beethoven thenpraised Liszts understandingin music.)

    (2) HARMONIC DICTATION:a.

    D+ d s l t d d m r t d

    I I IV V I I I ii V I

    b.

    A+ m m m f r d d d t d

    I I I ii V I IV I V I

    c.

    G+ s m d f r d r m r d

    I I vi ii V I V I V I

    Question (c) tests your ability to dictate a treble melody, and the ability to hear the 3 rdminor

    chord as a vi chord. The other minor chord we are used to is ii, which does not contain the

    tonic.

    Part B CADENCE (musical punctuations)

    (1) To create a cadence, two different chords are required. Take notes that the principal wayto create a cadence is moving from a chord without leading tone to a chord with the tonic,

    and vice versa:

    (2) Type of cadencesImperfect cadence = [,] or [?]

    I V [in minor key, iV]

    IV V [in minor key, ivV]

    ii V (not use in minor key)

    Perfect and Plagal cadence = [.] or [!]

    V I [in minor key, Vi]

    IV I [in minor key, ivi]

    Deceptive/Interrupted cadence = [;]

    V vi [VI in minor key]

    4. The interrupted cadence s V followed by VI, and is non-final. It is themusical equivalent of a comma, and may occur in the cottrseof a sentence,butnot at i ts end. Its rhythm rnay be strong to weak or weak to strong accordingto context. Refer also to chap. 2, para. 12 (d.Ex . 26 .

    5. The imperfect cadence.or half-close.appears n various forms, but i tssccond chord must be V. The following are tlrc forms at Present available :Major keys: I-V, ILV, tV-V, VLV.Minor keys: I -V, IV-V, VI-VNote lhat II-I' is not aaailable n the minrtr hey.This cadence is a musical semi-colotr.and is frequcntly used in the courseof a sentence.at the end of a subsidiary phrasc.

    13. No cadenceshould he immediately precededby its secondchord. Thus,the perfect cadenceshould not be precededby I, nor the interrupted (V-VI) byVI, nor any form of the inrperfect by V. Otherwise the effect of the cadencc smarred. The following are all poor :

    But this is poor, since V is insisted on too much. A better harmonisationwould be I I -V-I , as at Ex.3l (a). The sameprinciple appl ieswi th al l cadences.15. No chord may be repeated weak to strong, except at the beginntng of.a sentence16, If a melody note is repeatedor tied, try to get change of chor d on rherepetit ion. This is essentialweak to strong, brrt is not always-possible trong toweak.17. Avoid V-I except at beginning or end.18. The complete bassshould always be put in first, adding root-indicationssimultaneously. Start by inserting the bassol the f irst chord (which wil l be either

    I or V), and that of the t inal cadence normal ly V-I , but may be IV- i ) .19. As the remainder o{ the bass ls added, a warch must be kept forconsecutives.For example, f the harmonisationof the melody below hasprogiessedas shown :

    The next note to be treated (D) can belong o either II or v. But I l wil l giveconsecutiveoctaves n'i th the precedingbeat:

    Ex. 34.

    So V is the only possibil i t l ' .20. Bear in mind the constitutionwith, as these are alt good progressions,whether as actual cadencesor nbt. Forgot as far as:

    We find that the ensuing C can be harmonisedas either I, IV, or VI, andwe nced not hesitate to use VI, folkrwing V, since we already know that V-Vlis a satisfactory progression, being the interrupted cadence. In any case, V-I isundesirable (ser para. l7), while V-IV wil l give consecutive5ths.21. It is useful to jot down at the side of the exer cise he actual chordsavailable, so that it rnay be clearly and easily seen what are the exact possibilitiesfor the harmonisation of each individual note of the melody. The process s thento try each possible bass-note in turn, excluding those which would pro

    Step 1: determine all cadences

    Step 2: find out remaining harmonies

    Here we encounter a real problem. The soprano "A" cannot be harmonized effectively

    by either I or IV; both will create unwanted parallel interval: use of I will create //8ve

    with the ii chord on the third beat; use of IV will create //5th with first beat.

    SOLUTION: we are FORCED to use vi even we still want to stick with the first principle:

    use I, IV, ii and V only.

    I (//8ve)

    IV (//5th)

    The range of the bass is limited to a sixth. In general, do not make a voice part leaping too much.

    Step 3: fill up the inner parts; alto first and try to make it move in a consonant interval with the soprano. make necessary changes.
