Hail Mary

@hail_mary_bells is a bot for the American microblogging and social networking service Twitter which generates a score — loosely based on the American football pass of the same name — everyday for carillon (and carillonneur) 🔔 . Hail Mary is by composer, and artist Cory Arcangel↗, and published by Arcangel Surfware↗
The scores are free 😘 to be played at will by any carillonneur globally (please ping us below, and we can make a note of it!).
As part of Hail Mary’s inclusion in Oh, Gods of Dust and Rainbows, the 2022 iteration of the FRONT International: Cleveland Triennial for Contemporary Art↗, the piece premiered July 14th, 2022 in Cleveland in collaboration with carillonneur George Leggiero (and was played every day til Oct 2nd).
As part of Hail Mary’s inclusion in The Machine is Us, The MUNCH Triennale↗, IRL performances will took place in Oslo, Norway in collaboration with carillonneur Laura Marie Rueslåtten.

Hail Mary scores are generated daily, at 9 CET time and are posted to @hail_mary_bells↗. Please note, due to post Musk changes at Twitter the bot is down until further notice :/
The first line of the score is a row of completely random emoji 😉.
The second line of the score is fire emoji 🔥 which is a conceptual indicator of the “mood” of the beginning of the piece (see below).
The third+ lines are several lines of arpeggiated chords⚡ and a repeat # of those chords 🔂. The chords can be played anyway the carillioneur feels fit — simply arpeggiated, each note repeated alone, etc, etc. For example, ⚡️E D# C 🔁 x 8 can be played E D# C E D# C E D# C or E E E D# D# D# C C C,  or the notes can be re-arranged in any order such as, D# C E D# C E D# C E or D# D# D# C C C E E E, or even more broken apart(!) such as, E E D# E CC D#. The repeats can also be interperted in any way the performer sees fit as long as the relationship between the lengths of each chord 🔂 remain proportional. There are no octave markers, as the octaves are also completely variable, and the note played in the pedal (if any) is up to the perfomer as well. In short, the piece is written with alot of freedom in order for any and all carillionneurs to really go wild, or not, depending on their desire 💸☕️🎨!
Next is a line of ☁️ which is a mood indicator (see below).
After that is 🔙 emoji which is an indicator for the performer to reverse, and play the chords going back up the top of the Tweet. And lastly is another random emoji 🍎

The dynamics, harmonic content, and even placement on manual of the piece is losely based on a “hail mary” manuver in American football (no, for those wondering, this piece has nothing to do with the bible!), aka a very long forward pass — made out of desperation — when there is a very small chance of winning. Thus, the first chord should start on a crescendo on the bigger bells — as low as the instrument allows 🔥🔥🔥🔥🔥🔥 — then as the carillioneur progresses down the Tweet to the last chord, the carillonneur should move up the instrument to the very high bells. Some insruments with many octaves can have quite a ride up and down with this piece! Once at the last chord in the tweet, the performer should revrese ☁️☁️☁️☁️☁️☁️🔙🔙🔙🔙🔙🔙, and go back down the score backwards, moving again down back to the bigger bells in a crescendo.
The length of the piece is also up to the performer — from a few minutes to as long as the performer wants is all within the bounds 😘.
Furthermore, the entire piece (down and up the tweet counting as the entire piece) can be repeated as many times as needed, with a uniform style throughout, or with variations.
If the bot should crash (which can, and will happen!) please play the most recent Tweet ☕️.
