GHAR
Ghar, literally: home.
Ghar is also a term used in Guru Granth Sahib for two literary purposes: Ghar means a Taal (rhythm) used in a particular Raag.
Ghar is also a ‘note used in musical instruments’ e.g. in a harmonium. There are 12 notes in a harmonium, and, in Rabaab (rebec) there are 17 notes.
In Gurbaani, Ghar has also been used for heart/soul.
