Arabic time signatures

Some Arabic and Turkish music classical forms such as Semai use unusual time signatures such as 10/8. This may lead to an automatic grouping of notes that is quite different from existing typeset music, where notes may not be grouped on the beat, but in a manner that is difficult to match by adjusting automatic beaming. The alternative is to switch off automatic beaming and beam the notes manually. Even if a match to existing typeset music is not required, it may still be desirable to adjust the automatic beaming behavior and/or use compound time signatures.

Arabic improvisation

For improvisations or taqasim which are temporarily free, the time signature can be omitted and \cadenzaOn can be used. Adjusting the accidental style might be required, since the absence of bar lines will cause the accidental to be marked only once. Here is an example of what could be the start of a hijaz improvisation:

\include ""

\relative sol' {
  \key re \kurd
  \accidentalStyle forget
  sol4 sol sol sol fad mib sol1 fad8 mib re4. r8 mib1 fad sol
