▪ 節奏修正:要改正前半拍略長於後半拍的毛病。(可用節拍器及錄音分析)


CPE Bach Polonaise (安娜p.30)
▪ 波蘭舞曲屬較高階級舞曲(相對於Mazurka是農民舞曲),表情是驕傲尊貴勇敢的。彈奏的動作會比較大而果斷。練習波蘭舞曲首重節奏與精神。
▪ 較典型範例:蕭邦波蘭舞曲op.44升F小調。
▪ 第3小節是標準波蘭舞曲節奏型。
▪ 第5行可以較弱(柔)方式詮釋。蕭邦波蘭舞曲中段也常插入表情對比的段落(如op.44中間有一段Mazurka)

Burgmuller 9 (打獵)(preview)
▪ 第一行是典型獵歌起始:68拍弱起,節奏型態,簡單三和絃音(135),摹仿號角聲。
▪ 第5小節右手音型摹仿鼓聲。
▪ 第5~6小節左手有反向的號角五度(horn fifth)。號角五度是特殊而重要元素(example:貝多芬奏鳴曲告別No.26 Op.81a最開始3個音)。

Horn Fifths
A two-part HARMONIC progression, playable on natural horns or trumpets. The harmonic intervals are actually a minor sixth, a perfect fifth, and a major third (in C major):
Horn I C D E
Horn II E G C
The term horn fifth is obviously inaccurate, but it has been traditionally accepted. Examples can be found in innumerable works written during the last three centuries, in a variety of rhythmic patterns.
The trumpet calls in GIOACCHINO ROSSINI'S overture to William Tell is an example of rapid horn fifths. LUDWIG VAN BEETHOVEN'S Les Adieux Sonata opens with a slow, descending passage of horn fifths, illustrating the postillion horn announcing the departure of a stage coach.

▪ 關於號角五度:對位法(特別是巴洛克時期)中兩聲部進入五度必須反向進行,不能平行或同向(號角五度是少數例外)。原因是五度音過於和諧,若同向進入五度,兩條旋律線的進行特性會模糊(只剩下和聲性格)。後來作曲家若使用號角五度就明白表示有特殊意含。
