Anni-Frid 'Frida' Lyngstad, who lives in Zermatt, recorded the official song to mark the anniversary with Dan Daniell, a local singer.
The track '1865' was officially released on Friday as part of commemorations to remember the first climb of the fabled 4,478-metre Matterhorn peak by British alpinist Edward Whymper and his team.
"The song brings the dramatic race to the summit of the Matterhorn to life with the power of the chorale and its impressive lyricism," the town's tourist office said in a statement.
"It is the perfect soundtrack for an anniversary that will surely attract attention from all over the world," it added.
The track's words include: "Today's the day of joy, underneath a sky of blue…A dream was born of ice and stone, many years ago…they made it to the top."
One of the former Abba star's dedicated fans was so impressed by the track that they created their own music video to accompany the song, merging clips of interviews with the star and panoramic views of the Swiss Alps.
"My love and my Queen," commented another Frida-obsessive beneath the video's YouTube post.
"FRIDA is back!" wrote another.

Swedish commentators were less impressed by the latest offering by Frida, who sold over 380 million albums and singles worldwide with Abba and scored number ones across the globe.
"It sounds very dated, a bit like Enya," said one Swedish journalist.
In the song the pair are backed by a Zermatt-based group called Wintershome, which provides a chorus to the song composed by Daniell, whose real name is Urs Biner.
Biner is also a chef and owns the posh Alpine Chez Heini restaurant in the region.
Proceeds from the sale of the single will go to a foundation for children set up by Frida and Daniell that supports small projects in Switzerland, elsewhere in Europe and around the world.
Frida has shared a home in Switzerland with her British partner Viscount Henry Smith since 2008, having previously been married to Heinrich Ruzzo Prince Reuss of Plauen, a German Prince who died of lymphoma in 1999. She is also the ex-wife of Abba's Benny Andersson.
She has released a number of solo records since Abba split in the early 1980s.
