Beethoven's seventh symphony

[edit | edit source]

Visit YouTube/SMALIN to hear and see the first movement of Beethoven's 7th symphony: The lively Vivace takes dotted quarter note at 104 beats per minute ( = 104) in a Compound Duple Meter[1]. After a string of (often misleading) rhythmic hints, the pattern is establised at minute 4:16 in the youtube video. The theme is:

\new Score { \new Staff { \relative c''' { \set Staff.midiInstrument = #"flute" \set Score.currentBarNumber = #67 \time 6/8 \key a \major \clef treble \tempo 4. = 104 \bar "" e4.~\p e8. d16-. cis8-. \grace { cis32( } d4.)~ d8. fis,16-. gis8-. a4 a8 a8. b16-. cis8-. cis8( b4) \grace { cis32( b ais } b8.) cis16-. d8-. e4.~ e8. d16-. cis8-. \grace { cis32( } d4.)~ d8. fis,16-. gis8-. a4 a8( a cis) b-. a4 } } }
