新手音符認識 Musical Notes for Dummies

最近迷上了樂理,不斷地找有關的資料。我很喜歡Keith Sir 的講解,之前也跟大家介紹過他的YouTube頻道。他的樂理系列中,最先教的好似就是音符,了解音符對打拍子很有幫助。我們知道古箏是用簡譜的,不過未說簡譜,先用五線譜講解一下。(先說明,我對樂理也是白痴一名。看了很多影片和書,現在感到略懂一些。如有錯誤,還說大家幫忙指出來!)

先看上圖,不難理解,一個全音符的時值等如兩個二分音符。一個二分音符的時值等於兩個四分音符,如此類推。假如我們設定全音符的時值是四秒的話,那麼一個二分音符便佔兩秒,而一個四分音符便佔一秒。

以古箏而言,上圖就是一個很好的對照圖。一個全音符在簡譜上最常見的是一個音加上三條橫線 (1 – – – ),八分音符的在底下有一條橫線,十六分音符的有兩條橫線。全音符的時值最長,相對的說,底下愈多橫線最值愈少(即是需要彈得愈快!)。

For English speakers, there are many resources out there that talks about music notes. I am no expert in this area, but thought I would post this picture here for easy understanding.

Basically, the duration of whole note is equivalent to two half notes. The duration of a half note is equivalent to two quarter notes. When playing Guzheng, we often use JianPu (Numbered musical notation). The equivalent comparison is shown here:

For a whole note, it is shown as a note with three dashes (e.g. 5 – – – ). A half note is shown as a note with one dash (e.g. 5 – ). For an eighth note, it has one line underneath; for an sixteenth note, it has two lines underneath. A note with more lines underneath means the duration is shorter.
