time signature
The two numbers at the start of the music. The top number tells how many counts are in each bar; the bottom number tells which note gets one count.
6/8 time
A metre with six eighth-note counts in each bar, felt as two big beats (counts 1 and 4).
compound metre
A metre where each big beat divides into three, like 6/8.
dot
A dot after a note adds half of that note's value. A dotted quarter = a quarter + an eighth.
dotted rhythm
A long-short rhythm made with a dotted note, like ta-i ti.
fanfare
A short, bold piece, often played by brass instruments, to announce something important.
