Jazz Singing By Ear

Master a jazz standard and
scat solo in 10 weeks
Learn to sing jazz

without the theory-overwhelm

September 26th to December 4th, 2022

I know firsthand how intimidating and overwhelming singing jazz can be. There seem to be so many unwritten rules to follow that it feels impossible to know which notes to sing. You feel stuck and can’t figure out how to find the freedom and confidence to make a song your own, let alone improvise.

Instrumentalists are full of good advice, talking about scales and music theory. Unfortunately, that means very little to you, and you find it intimidating and overwhelming and are starting to doubt you can ever learn to sing jazz properly. You feel there is so much music and emotion inside you, but somehow you get lost when you let go, trying to express it.

You really want to improve, but you don’t know which steps to take as a singer to find the confidence and freedom you see others perform jazz on stage.

What if there is an easy to follow, bullet-proof way to

become the jazz singer and improviser

you dream to be?

  • Feel free and confident when singing and improvising jazz
  • Have clarity on how to learn a jazz standard and practice improvisation
  • Know how to swing and find notes that work
  • Know which songs suit you and how to find your keys on your own
  • Have your first jazz standard ready to sing at the next jam session
  • Sound like you when singing jazz and not like a copy of someone else
  • Know how to easily connect with your band and audience
  • Be ready and confident to go out and perform more
  • Having fun singing jazz on stage without feeling overwhelmed

“How knowledgeable you are, Heidi! It gave me the confidence to approach a musical career as a professional. In a way, you've made me more of a professional through this process.

I have something to teach because I've been taught so well. I can perform with more confidence, in my style because jazz is open to my interpretation with the foundation you've laid out in this course.

This is a thorough course on learning jazz by ear that will leave you equipped to perform a jazz standard as interpreted by yourself!

You'll understand the layout of the music and be able to talk about it with instrumentalists you work with. Free scatting will be easier with this knowledge. You'll easily learn some music theory even without lessons dedicated to theory. There's a lot of resources you'll use & learn about that will help you whether you're practicing alone or with a band."

“I love how Heidi communicates. She is clear and gives very good advice and good demonstrations. Thank you, Heidi, you're an amazing teacher"

Hi, I'm Heidi.

I am deeply passionate about jazz and helping you find your way to sing it with freedom and having fun doing it!

In this 10-week online training, I will teach you how to learn a jazz tune in an easy and practical way. You can apply this simple and tried process to any other tune and guarantee that you will sound authentic and true to yourself and the style.

In just a few weeks you will feel confident and free to sing your jazz tune with other musicians and safe to even improvise! All you need are your ears and a love for jazz singing. In jazz, we learn by doing - so be ready to take action!

For best results, be committed to invest about 25 min. a day into your craft. This time will consist of listening to music, practicing singing, training your ears and following the exercises laid out in the course. By the end you will have your first jazz standard and scat solo ready to sing at the next jam session.

This course is ideal for singers of all levels who want to learn a bulletproof way to feel self-assured and at ease in their jazz singing – on or off the stage. No prior musical training is necessary. You only need to be able to match pitch and sing a song without accompaniment.

These 10 weeks are more practical, easy and fun than my experience of 4 semesters in conservatory.

I have to say this course is priceless.

Since it was action drive course, a lot of inspirations gonna be posted in the Facebook group and you can get all the feedbacks, answers you want from Heidi and your accountability buddy.

Speaking of buddy, you can be friends with various genres, all levels of singers from all over the world. Not only that, you will find out how to sing jazz by just being yourself not just mimicking somebody else.

This is the course for every singer.

— Jekyll Joe

Times that work for

all schedules and time zones

The live coaching takes place from Monday, September 26th until Sunday, December 4th, 2022.

All lessons are pre-recorded. No need to attend live.

Video Reviews and Q&A Calls are not interactive. No need to attend live.

That way, you can take the courses at your own pace, regardless of what time zone you are in.

How does it work

Time is of the essence. To make sure you get the most learning out of Jazz Singing by Ear, Heidi aims to provide a schedule that works for you no matter which time zone you're in. Yet, she is making sure not to over-whelm you in the 10 weeks of coaching!

When are the lessons?

Every two weeks, on Monday, 10 AM CEST, you will get access to the new module videos on the course platform. These lessons are NOT live, but pre-recorded. You can then go through them in your own time.

In week 5 and 10 we will not release any new lesson, so you have a chance to catch up.

What about the Q&A Calls?

And the Video Reviews?

What happens after the 10 weeks of coaching?

What is a Hot Seat Call?

At the beginning of the week a Q&A post will go up in the Facebook group. Heidi will go live every other Monday to answer your most pressing questions, so you get additional support to the lesson material. All calls are added to the course platform, so you can watch them again later.

You are very much encouraged to post videos of your progress and get feedback from your peers. At the end of each module, Heidi will select 3 videos that she will discuss and review. She won't be looking for the best videos, but the ones she finds the group can most learn from. So, post your challenges, it will be rewarded.

You keep access to all lessons and call recordings until January 30th, 2023.

A Hot Seat Call is a two-hour group call where Heidi will answer as many questions from the participants as time allows. Participants have the chance to get on a "hot seat" with Heidi, where she answers individual questions. Hot Seats are given first come, first served.

What others have to say...

"The course was very well-structured and put together. Easy to understand and very confirming. It also taught me a lot of knowledge about jazz and where it came from. This course is a good and practical way to try out new things with your voice. Also, if you just want to know some more about jazz in general or how to approach to a tune...it is a great way to do so. Thank you for your commitment, Heidi. I had a lot of fun taking the course."

- Ina Rebhandl

"For Jazz aficionados and novices alike, I think it's a great way to know more and love more about jazz singing. The lessons are compact and full of practical tips and jazz knowledge. The best thing about the course was The deeper appreciation and understanding of Jazz and how to perform it."

- Odessa Patron

"This course is great because you can do the lessons in your own tempo and at home. Heidi is really experienced and knows what she's talking about. Even if it is an online seminar, you can always ask questions and even if I did not ask one, I read some questions and answers on Facebook and found them really helpful for me too.
Another pro for me was to "meet" so many singers from all over the world. To have the knowledge from a big group in one place is definitely a big plus!

- Beate Schmidt

"This is a wonderful course to take because Heidi really breaks things down into edible bites for us to try. Take notes. I can re-listen to things Heidi spoke to. There is a lot of information receive."

- Dana Reedy

"For beginners, this course builds a foundation for you about jazz. But if you already know a lot more about jazz, you could still pick up things in this course. It gives you a new point of view to see Jazz."

- Naomi Yu Kainzer

"If you are interested in jazz and how to approach a song in order to sing it and to improvise on it, you should try out this online course. Heidi offers some clear and structured instructions and you can then decide how fast or slow you proceed. The other singers that join the course will give you an idea of the different interpretations and levels where you can be."
