✔ 最佳答案
transposing instrument 即係移調樂器, 咁non-transposing instrument 就係非移調樂器
兩者既分別就係, non-transposing instrument 例如鋼琴, 小提琴, 樂譜寫既音係C 音, 當你演奏出黎聽落就係C 音, 但係Transposing instrument 例如clarinet in A, 當樂譜寫既音係C 音, 演奏時聽落就係A 音.
而有D transposing instrument, 如clarinet, 都可以移唔同既調, clarinet 可以係
clarinet in b flat (譜寫C 音, 當你吹哩個音聽落就係b flat)
clarinet in a (譜寫C 音, 當你吹哩個音聽落就係 a)
clarinet in e flat
clarinet in d
bass clarinet in b flat (譜寫C 音, 當你吹哩個音聽落就係再降一個八度既 b flat)
bass clarinet in a
有好多樂器都係transposing instrument, 如clarinet, english horn, trumpet, etc......所以要記
問transposing instrument 係 樂理試題好常見, 如2007A,3c (4) 佢問你所填既樂器係咪transposing instrument, 2007B, 4c (2) 問bassoon 係咪transposing instrument, 所以考之前一定要搞清楚邊d 係transposing
2007B
4b 1 (好難描述)
問題指係樂譜上括住 A, B, C 既位置係Root position 既tonic triad, 要你填返佢地既key
括號A (音: A, C, E), 問題話哩三個音係Root position tonic triad, 樂譜上, A 音係低, 所以A 音係Tonic (1音), 所以個key 一定係A Major 或A Minor, A Major 應該有三個sharp (F sharp , C sharp , G sharp), 但括號A 裏面既C 音冇Sharp 所以個key 就唔會係A Major, 所以答案係A minor
括號B (音: C, E flat, G), 根據樂譜, C 音係低, 所以C 音係Tonic, 個key 會係c major 或 c minor, c major 應該係冇sharp, flat, 但括號B 有e flat, 所以答案一定唔係c major, 應該係c minor
括號C (音: B flat, D flat, F), 同樣做法, b flat 係tonic, 個key 會係b flat major or b flat minor, 個key 係b flat major, 只有兩個flat, 分別係b flat 同e flat, 但係括號C 有d flat, 所以答案係b flat minor
描述得好複雜, 唔明可以再問
4b 2 圈起所有係bars 6-7 piano part 既major chords
首先你要知點分個chord 係major, minor, augmented 定diminished
major chord 係major 3rd (由root 數到3rd 係4 semitone, 四個半度) perfect 5th (由root 數到 5th係7 semitone)
如果有 c (root), e (3rd), g (5th) 三個音, c 到 e 係4 semitone, c 到g 係7 個semitone, 咁哩個就係major chord
係bar 6 第一個chord, 係A, C, E, 由A 數到C得三個Semitone (唔係major 3rd), 由A 數到E 有7個Semitone, 因為佢乎合唔到major 3rd 既要求, 所以唔係major chord
piano part 之後果三組chord 一樣咁樣數, 你試試做唔做到
答案係bass clef 之後果個chord 同最後結尾既chord
4b 3, 寫出piano part, left-hand note 最低果個音 (letter name 即係A, B , C, etc....), 咁你係睇左手果part, 由頭睇一次, 睇下邊個音最低, 答案係 F

ps. 你之前都有問過有關brass 既問題, 我以為你係自學, 但如果你係有跟樂理老師學, 你可以跟錯老師, 正常既樂理老師冇可能會唔識, 因為係grade 5 樂理一定會問既野
有其他問題可以email 俾我:

如果你係黎緊星期六考, 就要加緊溫習同多做past paper, 唔明記得要問, 如果遲d 考, 你應該考慮轉老師
