From picnicking at Glyndebourne to tippling a Riesling in the Rheingau region of Germany, summer in the Northern Hemisphere is a great time to relax and hear an opera or a favourite jazz performer at festivals anywhere from the Swiss alps to Johannesburg.
Here is a selection highlighted by Reuters journalists.
Glyndbourne, Lewes, England, May 17-Aug 24
It's famous for its traditional English-style hamper picnics on the beautifully manicured lawns and at tables on the exterior balconies of the opera house.
But it is the music-making that goes on inside that really counts. Productions this year include Strauss's "Der Rosenkavalier", Tchaikovsky's "Eugene Onegin", Handel's "Rinaldo" and Verdi's "La Traviata".
But what sets the Glyndebourne regulars' hearts aflutter are the productions of Mozart for which the house is justly famous, and the two this year are "Don Giovanni" and "La Finta Giardiniera" that had its premiere in 1775 just before Mozart's 19th birthday. Tickets £50 to £215 (NZ$98 to NZ$420).
Rheingau Music Festival
Various venues, Rheingau region of Germany, June 28-Sept 13
This in some respects is a wine-region tour with a music festival attached, with so much going on it boggles the mind. Suffice to say that a festival that can encompass everything from an opening concert tribute to Shakespeare's birthday with sopranos Miah Persson and Golda Schulz to jazz great Bobby McFerrin "and friends" to a kiddie concert featuring Bert and Ernie, the Muppet characters from "Sesame Street", is eclectic, to say the least.
Other names on tap include pianist Pierre-Laurent Aimard and violinist Julia Fischer, while the festival's composer and artist in residence is Jorg Widmann, a top-notch clarinetist and cutting-edge composer all in one.
A rolling feast of fun, an hour's drive from Frankfurt and with ticket prices in the €15 to €80 (NZ$23 to $125) range. And don't forget to sample the Riesling.
Istanbul Jazz Festival
Istanbul, Turkey, July 1-16
Fans of the TV series "House" can catch its star, Hugh Laurie, on the piano at Istanbul's annual jazz festival. The actor is a versatile musician who has settled on the keyboard with his blues-inspired Copper Bottom Band.
Rising stars such as Cecile McLorin Salvant, the 25-year-old Grammy nominee whose vocals have been compared to Billie Holiday and Sarah Vaughan, and Brooklyn-based, rock-influenced bandleader and composer Darcy James Argue also perform at the festival staged by Turkey's most venerable cultural institution, the Istanbul Foundation for Culture and Arts (IKSV).
Benin singer Angelique Kidjo and psychedelic Turkish folk rock group BaBa Zula also take the stage at venues across Europe's biggest city, including city parks that will host free concerts. Tickets range from 20 lira (NZ$10.7) to 350 lira.
Aix-en-Provence, France, July 3-24
Cited as best opera festival at the International Opera Awards this year, Aix-en-Provence almost always provides at least one production that sets the opera world abuzz.
In 2012 it was the world premiere of George Benjamin's searing "Written on Skin", last year it was the final production by the late French director Patrice Chereau of Strauss's "Elektra". What it will be this year is anyone's guess, but the offerings on tap are Mozart's "Magic Flute" directed by Simon McBurney, Handel's "Ariodante" in a production by Richard Jones and Rossini's "Il Turco in Italia" staged by Christopher Alden.
All this is interspersed with a wide spectrum of musical offerings that will include a staging by artist William Kentridge of Schubert's song cycle "Die Winterreise" sung by baritone Matthias Goerne with Markus Hinterhauser at the piano and Katie Mitchell's staging of J.S. Bach's "Trauernacht" cantatas with soloists and instrumentalists of the European Academy of Music.
Tickets €30 to €120 for recitals, €30-€250 for operas.
Love Supreme Jazz Festival
Glynde Place, Lewes, England, July 4-6
With star attractions including Soul II Soul, Imelda May and De La Soul, this boutique event set deep in the Sussex countryside is stretching the boundaries of what might be considered "jazz" but there is plenty of instrumental twiddling elsewhere on the bill to keep the aficionados happy.
It's a well-shod event, graced by a champagne-and-oyster bar as well as the more usual festival fare, and its location in a posh corner of rural England helps explain why many in the crowd - men in red trousers and women in cashmere pashminas - could be refugees from upper-crust events like the Henley Regatta.
Its backdrop of the South Downs and Elizabethan-era Glynde Place are a picturesque setting for some top acts. Prices range from adult daily tickets at £60.50 to family VIP including camping at £540.
Montreux Jazz Festival
Montreux, Switzerland, July 4-19
The 48th edition of one of Europe's most prestigious summer music events - dubbed the "Rolls Royce" of festivals by former co-director Quincy Jones - offers great jazz and rock (albeit it at steep prices), stunning views of the Swiss Alps and easy transport.
Pharrell Williams (July 7) and Stevie Wonder (July 16 but with tickets are up to 450 Swiss francs (NZ$577)) are the sold-out headliners but the box office always has limited tickets on the night of each concert to cut down on scalping. Outkast, Massive Attack and Jamie Cullum are also booked in Stravinski Auditorium, with smaller groups playing in the Jazz Club or Jazz Lab where entry is 100-200 Swiss francs.
The 'Brazil Boat' event on July 13, music while crossing the lake, is a reasonable 65 francs. In addition to the indoor concerts with great acoustics, there are free festival outdoor concerts along the shores of Lake Geneva, dotted with food stands.
The Chateau de Chillon, made famous by English poet Lord Byron with his poem on the prisoner, is a short bus ride or walk. Going for a swim or sailing in Lake Geneva can be delightful.
Perugia, Italy, July 11-20
Italy's music scene shows it has more to offer than nights at the opera in July as the hilltop town of Perugia in the middle of the "boot" plays host to an altogether more unruly genre for Umbria Jazz.
Festivities kick off on July 10 with a charity football match between two teams formed entirely of musicians - Nazionale Italiana Cantanti and Nazionale Italiana Jazzisti.
American jazz greats Herbie Hancock and Al Jarreau will please the purists, while hip-hop group The Roots become the first rap act to play at the festival in its 37-year history. Ladies' night features Natalie Cole, daughter of the late Nat King, and a day dedicated to Italian artists will be topped off with a tribute to film music composer Armando Trovajoli. Hit "Techno-Logical", the festival within a festival where live DJs play dance music non-stop from 4pm to 4 am.
Pay a visit to the Perugina chocolate factory museum or visit the 16th-century fortress known as the Rocca Paolina. Tickets to different events €10 - €55 euros.
Verbier, Switzerland, July 18-Aug 3
This festival making efficient summertime use of a Swiss ski resort has been described as the music world's equivalent of the annual Davos economic summit - and for good reason.
Pianist Martha Argerich has been a regular since the festival started 20 years ago, and her august presence assures not just a high standard of music-making, but also the recruitment of an elite crew of musicmakers.
This year's crop includes cellist Steven Isserlis, guest conductors Marc Minkowski, Ivan Fischer and Daniel Harding, pianist Evgeny Kissin and singers Vittorio Grigolo, Thomas Hampson, Rene Pape, Eva-Maria Westbroek, Ramon Vargas and Rolando Villazon.
There's also a world music night with Senegalese troubadour Youssou N'Dour to leaven the loaf. Ticket prices 45-180 Swiss francs. Hotel space is not cheap but is available, thanks to the ski resort locale.
Salzburg, Austria, July 13-Aug 31
This year's Salzburg Festival continues the tradition at one of the world's most prestigious music venues of being cutting edge and dripping with luxury at the same time.
For those who want to know where opera is going, French composer Marc-Andre Dalbavie, steeped in the spectral school, teams up with librettist Barbara Honigmann and director Luc Bondy for "Charlotte Salomon", based on the work of the Jewish artist gassed at Auschwitz.
For those who take their opera star-powered, Anna Netrebko and Placido Domingo pair up for a new production of Verdi's "Il Trovatore" by Alvis Hermanis. Throw in "Der Rosenkavalier" directed by Harry Kupfer for the occasion of Strauss's 150th anniversary, and Gustavo Dudamel conducting in the festival's parallel concert series, and it is a festive time indeed. Prices 16-420 euros.
Lake Constance, Austria, July 23-Aug 5
The Bregenzer Festspiele on the shore of Lake Constance in western Austria features Mozart's "The Magic Flute". The festival runs from July 23 to August 25 this year, with the premiere on July 24.
David Pountney is artistic director for the event, whose spectacular sets on a stage perched above the lake make for dramatic viewing.
Tickets start at €29 and go up to €300. The show goes on even if it is raining lightly. Organisers recommend bringing waterproof clothing rather than umbrellas, which block the view.
Utrecht Early Music Festival
Utrecht, Netherlands, Aug 29-Sept 7
Now in its fourth decade, the festival in the picturesque university town builds on a strong Dutch early music tradition, built up over decades by great performers such as the late harpsichordist Gustav Leonhardt.
This year, the festival focuses on the baroque composers of the Habsburg lands, in particular the music of Baroque-era Prague and Vienna. Visitors can listen to live performances of works by some of Bach's and Handel's most accomplished contemporaries, including Isaac, Biber, Fux and the Bohemian composer Zelenka.
Highlights include performances by violinist Gunar Letzbor and his ensemble Ars Antiqua Austria, and Vaclav Luks's ensemble Collegium 1704 playing baroque repertoire from Prague. Tickets €10-€36.
Odessa, Ukraine, Sept 11-14/Koktobel, Crimea, Sept 12-15
After 11 years of being one of the largest music festivals in the post-Soviet region, following Russia's annexation of Ukraine's Crimea in March, the open-air jazz fest in the resort town of Koktobel has split into two events.
The Koktebel Jazz Festival will take place Sept. 11-14 in Zatoka and Bilhorod-Dnistrovskyi, in Ukraine's Odessa region, some 50 km from Odessa. Britain's Get the Blessing is among the headliners, and remaining tickets available via the website are going for 599 hryvnias (around NZ$58).
The Koktebel Jazz Party will take place Sept. 12-15 in Koktebel, a resort town in southeastern Crimea. Tickets are not available yet, but organizers say they will be sold by the peninsula's Moscow-backed authorities and proceeds will go to the local government. The Jamal Thomas Band (USA), Deborah Brown (USA) and Valery Ponomaryov (USA) are among the headliners.
Joy of Jazz
Johannesburg, South Africa, Sept 25-27
South Africans are steeped in music and even wintry weather will not keep them away from a good groove. Dianne Reeves, Billy Ocean, Delfeayo Marsalis, Gregory Porter and Roy Hargrove will feature at the 14th installation of the annual festival. South African stars include Sibongile Khumalo and Jonas Gwangwa.
The venue is moving away from the downtown Newtown precinct to the Sandton Convention Center. A two-day pass costs 1,250 rand (NZ$134) If all the dancing doesn't leave you bone tired, head out to Soweto and check out Vilakazi Street, former home to two Nobel Peace laureates.
Take a tour of the Mandela House museum then try some tripe at the vibrant Samkhumzi Restaurant, a stone's throw away from Archbishop Tutu's residence. For more on South Africa's apartheid past, stroll over to the Hector Pieterson museum or visit the Apartheid Museum close to downtown Johannesburg, or Liliesleaf Farm and Museum in Rivonia.
