A few days ago, broadcaster RTP confirmed the Portuguese participation in the Eurovision Song Contest 2019 in Tel Aviv.
In one go, they also stated they would be using their national final Festival da Canção again.

Festival da Canção 2019 will feature 16 songs in total, divived over two semi-finals.
With 8 songs competing per semi-final, 4 from each show will make it to the final, making the total over there 8 once again!

Out of those sixteen, 14 songs will be written by composers directly invited by RTP.
These composers have complete freedom as to what the song will be like (in regards to style or language), as long as it adheres to the Eurovision rules. As in previous years, they will also be the ones themselves to choose the performer(s) for their song!
As for the remaining two entries: one will come from the competition for new composers by Radio Antena 1 and the other one from an open call of entries, of which a jury panel from RTP will pick the best one to be the 16th and last entry to compete in Festival da Canção 2019.
These 14 composers, RTP confirms today, have already been chosen and approved.
The Portuguese broadcaster also adds that these composers, from different genres and all newcomers to Festival da Canção:

[…]will bring greater diversity [to the contest], approaching what is done in Eurovision, bringing 14 new faces to the show.

The two semi-finals are currently scheduled for the end of February with the final expected at the beginning of March.
While the semi-finals will be taking place in the RTP studios in Lisbon, RTP revealed that the final will be held in another city! Last year, while the Eurovision final was organised in Lisbon, the final of Portugal’s own national selection took place in Guimarães.

The list of composers is expected to be released in November or December and RTP promise that the variety of composers will bring new musical styles to the show!

Last year’s Festival da Canção was won by Cláudia Pascoal, who sang the delicate ‘O jardim’ on home soil in Lisbon:
