Adam Neely mentioned this book in a video called The Worst Jazz Solo of All Time. It is a collection of short essays about different listening and playing practices. In the introduction, Mathieu mentions his hope that you will keep returning back to the book and taking new things from it every time. Here are 12 practices that stuck with me on this read through.
1) Symphony of Place: Combination of mindfulness practice with prose writing. Open your listening to your environment, and then narratively, non-judgmentally, write the things that you hear.
2) Chanting: Mindfully repeat a syllable (e.g. Om, Sa). Try to settle on a single sustained pitch. "You will hear your own overtones at the fringes"
3) One Note After Another: Play a note, hold it and listen intently. Get lost in the landscape of the sound, and scrutinize every detail. When you have heard all you can hear, play another note. Repeat until the experience is reliable. "There will be a moment when your sense of fullness gives you permission to go on to the next note). A connection between the notes eventually emerges. "If you find yourself trying to make a melody, stop. [...] Let the melody make itself, let the sounds choose the sounds. " (Don't be seduced by the melody is the instruction, but really it is OK to go ahead and be seduced, it's only love.)
4) What should I practice: The secret is to keep track of what you do practice, like an anthropologist would. Generally guideline is to spend 1/4 of your time on each: Playing other's music, Theory & Technique, Improvising & Composing, and Listening.
5) Lentus Celer Est: Slow is Fast.
6) Finding a Teacher: Reflect on the person you want to become - "Try to capture the character of your future music in your ear, even if the notes are a blur. [...] When the picture comes into focus, describe it in writing. Tell everything." What has to happen for you to become the person you saw? The person who can guide you there is the teacher you need to find.
7) Singing in Unison With a String: Like the chanting exercise, but first play an open note (doesn't need to be on a string) listening until it fades, and then try and sing that note in unison with the string, make your voice like the string.
8) AMAPFALAP: As Much As Possible From As Little As Possible. Improvisation with one note. So many variations possible: Dynamics, Duration, Timbre, Texture, Feeling & Intention. Eventually, do it with two notes, and then three, four, across octaves. But don't forget about the things you learned when you were only using one note! Another note is another tool in the toolbox, don't forget about the other variations.
9) Touch What You Sing: Strike one note on your instrument, then a second. Compose a brief melody with only these two notes. Then, continue improvising, but now sing what you are playing. Sing at the same time as you play the note, blend your voice with the sound of the instrument. Then, expand to three pitches and believe you are simultaneously singing and playing short passages of real music. Now, instead of pressing the key all the way down, merely touch it - the only sound is your singing but keep going through the motions of playing the instrument. Touch the keys and sing the notes that would sound if you were playing the instrument. If you're unsure of your accuracy, play a note to check it. Sing what you touch, then Touch what you sing, following your voice. This "gives priority to the inner world and asks the outer world to mirror it faithfully. You can then add more notes gradually (this is a life of work, don't rush!) You can play the root note to keep it in the air and stabilize your singing.
10) Play by the Clock: Improvisation and composition practice. Set a timer for exactly one minute and watch it while you play, realize you are half way done at 30 seconds, and that you need to start wrapping up at 45 seconds, at 55 second you need to be concluding. Try to finish the piece at exactly 60 seconds.
11 )Just the News: Improvisation practice - remember a scene or event you saw within the last 48 hours, take some time to mindfully remember what happened and then improvise a short piece that is like a journal entry for the event.
12)The Magic Scale: You don't need to be constrained by the modes, you can make your own mode using: C Db/D Eb/E F/F# G Ab/A Bb/B C - Root and Fifth are given, but for the other degrees let how you feel like playing decide which to choose.
