ספירת העומר - S&P - London [EA]

ספירת העומר - ברכת המצוה - S&P - London [JC]

During the ספירת העומר period, the following melody is used for לכה דודי [MF], as well as for שיר המעלות [MF, music SF] in the Western אשכנזי tradition.

לכה דודי - ספירה [KAJC] {a little slower than usual}

לכה דודי - ספירה [HB] {Dutch variant}

לכה דודי - ספירה [CG]

יגדל - ספירת העומר - Netherlands
