| A knowledge of chord progressions will help you communicate and play with other musicians. |
擁有和絃進行的知識能幫到你們和其他音樂家溝通和演奏。 |
| It is a must for participating in any kind of jam session. |

| Knowing the most commonly used chord progressions and forms allows for greater enjoyment and unity when playing with other musicians. |
懂得最常用的和絃進行和變化會讓你們玩音樂時更享受。 |
| Most songs use three or more chords though some songs exist that only use two chords. |
大部分歌曲運用三個和弦或以上，不過也有歌曲只用兩個。 |
| Often musicians will embellish chords by adding or removing notes and to provide further interest may vary the rhythm. |
通常音樂家喜歡加或減去一堆音來點綴旋律。 |
| One chord "structures" are uncommon but they do exist. |
單一個和弦的“結構”雖然不常見，但也存在。 |
| For instance, Frere Jacques is a one-chord song because it can be played against a single major chord. |
譬如，“兩隻老虎” 的旋路只有一個和弦，因為它可以用一個大調和弦奏出。 |
| The melody "Taps", traditionally used at American military funerals, and which is very evocative, consists only of the notes which comprise the C-major chord (C, E, G). |
”Taps“ 這首歌的旋律通常出現在美國軍人的喪禮裏，讓人歷歷在目，但他只有C大調裏的三顆音 （C，E，G）。 |
| One chord songs are rare on guitar. |
在吉他上，一個和弦的歌比較稀有。 |
| The most common chord progression is the I-IV-V. |
最常用的和弦進行是 I-IV-V. |
| Note that Roman Numerals are used to describe these chord progressions. |
請留意：一般會用羅馬數字來寫和弦進行。 |
| Many songs use only these three chords. |
很多歌曲只用三個和弦。 |
| If one views chords as a set of balancing scales with the root note and octave root at opposing ends it will be noted that the IV and V chords are at equal distance respectively to the root and octave root. |
如果把和弦當一套在天秤上的音，一邊是跟音另一邊是高八度的跟音，你會發現 IV和弦 和 V和弦 的距離跟音和高八度的跟音是一樣的。 |
| Take for example the key of C major: |
例如在C大調裏： |
| C - D - E - F - G - A - B - C |
C-D-E-F-G-A-B-C |
| You will see that the G note (or chord) is a fifth above the root note. |
你會看到G音（或者和弦）是跟音的五度。 |
| The note F is a fifth below the octave. |
F音是高C的低五度。 |
| This movement of a fifth is very pleasing to the human ear in its sense of balance and cohesion in relation to the root note. |
這個五度的和弦變化非常悅耳，而其中是因為那非常平行的感覺。 |
| Another way to view chord progressions is that of a journey. |
另一個方式去理解和絃進行是一個旅程。 |
| In the sense that the root (or tonic) chord is the starting point and the octave root is at the end. |
跟音是起點，八度是終點。 |
| All other points (chords) provide interest and variation with the fourth and the fifth chord occupying a special place on the journey due to them being half-way. |
其他和弦全都把和弦變得更有趣，而第四和第五和弦是旅程裡較特別的，因為他們都是中間點。 |
| Many chord progressions start at the tonic (I), moves away to somewhere else, only to come back to the tonic. |
和弦進行多數在跟音（I）開始，然後出發去其他不同的和弦，再回去跟音。 |
| You can play this progression with major chords or you can substitute minor chords for the IV or V. |
可以用大調彈這個和弦進行，或把大調的和弦改成小調IV或V。 |
