Tourism bosses say that piping and drumming enthusiasts have contributed £10million to Glasgow's economy this year.
Around 8000 musicians visited the city from virtually every corner of the globe to make up 225 bands who competed in the World Pipe Band Championships on August 11, and the week-long Piping Live! festival.
More than 50 of the bands travelled from overseas, including Pakistan, Brazil, Eastern Europe, Oman, Sweden, America, Canada, Australia and New Zealand, to take part in the prestigious competition on Glasgow Green.
The championships have been associated with Glasgow since 1948 and are a celebration of the very best of Scottish music, culture and dance.
But they will also result in a £10m cash boost for the city as a result of spending on hotel rooms, restaurants, shops and entertainment. Last year's competition attracted a record 50,000 spectators and won the Scottish Traditional Music Awards' Event of the Year title.
Tourism bosses say the World Pipe Band Championships have grown into one of the major events on the city calendar.
The championships are organised by the Royal Scottish Pipe Band Association, whose chief executive Ian Embelton was at Glasgow Airport on Tuesday to greet some of the bands flying into the city.
He said: "In the past 10 years the event has grown and grown and all the top performers around the world now make sure they attend.
"The economic impact of the event is around £10m and every hotel, restaurant, shop keeper, publican and taxi driver says it is a fantastic event financially and for atmosphere.
"The Edinburgh Military Tattoo is a fantastic event, but no other city could bring together 8000 musicians. There is nothing even close to it anywhere in the world."
So many people tuned into a BBC documentary about the event last year that this year's is also to be filmed and will be broadcast on August 19.
A Glasgow City Marketing Bureau spokeswoman said: "We are delighted to welcome the World Pipe Band Championships back to Glasgow.
"The city is buzzing with activity and with the arrival of performers and spectators from across the globe, local hotels are set to be extremely busy over this weekend."
Chamber of Commerce chief executive Lesley Sawers said: "Glasgow is building an international reputation in hosting major events and the success of Piping Live! is another example of the strength and appeal of the city."
