These days I pretty much play everything by ear, but was originally trained in strathspey and reel violin so realise I should know the answer to this, but I can't remember what, if any, the practical differences were. Is there any difference between a score marked 4/4 and one marked 8/8? Or is that sort of thing only useful to indicate a time signature change within a piece of music? |

A time signature is simply the composer's way of telling you how s/he is subdividing the measure. So in 4/4 time, the composer imagines the measure divided into four beats, while in 8/8 time, the composer imagines the measure divided into eight beats. The difference is less in the strict timing and more in the feel or pulse of the music. Try counting these out loud: 4/4 time: "1-2-3-4-/1-2-3-4-" 8/8 time: "12345678/12345678" 2/2 time: "1---2---/1---2---" All three of these take up exactly the same amount of time, but to me, the 4/4 time feels steady, while the 8/8 time feels brisk and the 2/2 time feels stately. In all three time signatures, a quarter note will have the same value---one quarter of the measure---but in 4/4 time, it represents the pulse of the music, while in 8/8, it's two pulses and in 2/2 time, it's half a pulse. A difference in feel between 3/4 and 6/8 time can be even more obvious. In 3/4 time, the measure is broken up into three distinct beats, as in a waltz. In 6/8 time, by contrast, the measure is often broken up into two beats, each with a triplet feel. Like this: 3/4 time: "ONE and TWO and TRE and/ONE and TWO and TRE and " 6/8 time: "ONE two tre FOR fiv six/ONE two tre FOR fiv six " If the composer writes three quarter notes in 3/4 time, it will feel like three notes on the beat. But if the composer writes three quarter notes in 6/8 time, the second note may feel syncopated relative to the overall pulse of the music. |

In 4/4 time, the concept of pulse is assigned to the quarter note beat. However, in 8/8 time, which would seem to be similar, the sense of pulse is completely open-ended. Often time signatures in 8 have a dotted quarter note pulse, such as 6/8, 9/8, 12/8, but in a time signature like 8/8, which is not historically used, the composer is free to subdivide as they choose. This could technically be any variation of 3+3+2. Basically, the difference is in the subdivision. |

There is one commonly-used time signature that is just wrong. 6/8 literally means that there are six beats in the measure, and an eighth note gets one beat. Almost always there are two beats in the measure and a dotted quarter note gets one beat. But there is no readable way to write that. 2/(8/3)? 2/2.666? |

In 8/8 rythm, each quaver note recieves one beat, with the accent on first beat and fifth beat in a bar. |

As an arranger, I have once used 8/8 as a time signature. I wanted the performance to emphasise the nature of the quaver as the pulse, while recognising that the melody was easier to recognise as 4/4 than 4/8, thus preserving its legato style. 8/8 also led to a saner tempo marking... |
