Mendelssohn: Octet in E-flat, Op. 20

Eight strings playing as one band, not two quartets side by side. Thrilling to read with a strong first violinist and a group that likes to play fast and light; the other seven parts are more manageable.

Part by part

The piece is rated by its hardest part. Here is how each part compares, so a group can see who will need to practise most.
Violin 1
A concerto-like part: high, fast and leading almost everything, from the soaring opening to the running notes of the finale. Choose this player first.
Very demanding
Violin 2
Often doubles or answers the first violin, with plenty of quick passagework of its own, especially in the scherzo and finale.
Advanced
Violin 3
Mostly inner harmony and rhythm, with its share of the fugato entries in the finale. Easier on the fingers, but it needs to stay light.
Intermediate
Violin 4
Similar to the third violin: tremolo, repeated notes and fugato entries. A good seat for a solid player reading the piece for the first time.
Intermediate
Viola 1
Gets real melodic moments and busy inner lines, and is very exposed in the quiet, transparent scherzo.
Advanced
Viola 2
Mainly filling in harmony and rhythm. The challenge is keeping repeated figures soft and even.
Intermediate
Cello 1
Joins the lower strings when they restate the opening theme, and has quick, exposed figures in the finale.
Advanced
Cello 2
Starts the finale’s fugato, so the whole movement depends on a clean, confident first entry. Elsewhere mostly the bass line.
Advanced

The movements

I. Allegro moderato ma con fuoco. The first violin’s theme rises over a shimmering tremolo. Long and full of energy; “moderato” is a warning not to start too fast.
II. Andante. A gentler, slower movement. The easiest place for eight people to listen to each other and settle balance.
III. Scherzo: Allegro leggierissimo. Quick, quiet and as light as possible. Short bows near the string, and nobody should play louder than the marking.
IV. Presto. Opens with the fugal subject in the second cello, passing up through the group to the first violin. Fast and relentless, with brief reminders of the scherzo along the way.

Reading it together for the first time

Start with the Andante to get used to the size of the group, then try the scherzo slowly before attempting it at speed.
Seat everyone as one ensemble, not as two separate quartets: the first violin leads the whole octet.
Print all eight parts from one edition. IMSLP has complete sets of parts from several publishers.
Book a room with space for eight chairs, eight stands and two cellos’ worth of spikes. Half an hour to play through, so two hours is comfortable.

About the piece

Mendelssohn finished the Octet on October 15, 1825, when he was sixteen. It was a birthday present for Eduard Rietz, his violin teacher and friend, who was given the autograph score. He later revised it, and the version usually played today is the one published in 1832.
Mendelssohn may have had Spohr’s Double Quartet, Op. 65, in mind, but there the two quartets play as separate groups; here all eight players form one ensemble. He asked for it to be played in a symphonic, orchestral style, with louds and softs sharper than usual. His sister Fanny linked the scherzo to a passage in Goethe’s Faust. Snatches of it come back in the finale, which opens with an eight-part fugato that borrows a line from Handel’s “Hallelujah” chorus.
