When the Festival is held
The Montreal Jazz Festival is held annually, roughly between the last week of June and the first week of July. It lasts a total of about 10 days, during which the city “dresses up for parties” to welcome hundreds of thousands of tourists.

If you want to go to Montreal for the festival, you need to book at least 6 months in advance.
Free Concerts
Is very popular with everyone also because most of the concerts are free. Yes, it seems impossible, but while in Italy you pay an average of 80 euros for a concert, in Montreal you can hear the greatest musicians in the world play for free.
In addition to free concerts, there are several paid concerts, although you will probably see so many events that you won’t even find time to attend the paid ones. These are obviously more exclusive events, collected in some club or theater.
Music is free, but not everything else, in fact restaurants, hotels, guesthouses and shopkeepers work at full capacity, and the prices are not always very affordable.
Advice
The secret to witnessing this event is timing, or to put it as a musician, it’s all about the “Rhythm”.
In fact, first of all, as we have already written, you must organize your trip at least 6 months before, if not more, because Montreal, in this period, literally explodes with tourists. Even to attend the concerts you have to move in time. In fact, the seats are few, compared to the number of spectators, and even if you want to attend a concert while enjoying dinner, you must always move well in advance.
So go for lunch and dinner early, and arrive at least an hour early if you want to comfortably attend the concert that interests you most.
